Kashrut (Kosher) kasher kosher. Often used when referring to the process of making meat kosher by washing, soaking, and salting it in a prescribed fashion. This must be done before it can be cooked, to drain the flesh of as much blood as possible. Today, most kosher meat comes already kashered, ready to be cooked and eaten. Kasher also refers to the process of heating and cleaning utensils and dishes so that they can be used for kosher cooking. It can also refer to cleaning a kitchen and its contents of hametz in preparation for Pesach. For example: “He poured boiling water over all the silverware to kasher it for Pesach.”kashrut kosher can eat. Usually used in the phrase “to keep kashrut.”kosher 1. The general term used to describe foods that are acceptable according to the Jewish dietary laws. The basic laws of kashrut are set forth in the book of Leviticus in the Torah, which contains a list of all kosher and non-kosher animals. Meat must come from an animal with split hooves that chews its cud (for example, cow, lamb, deer) and that is slaughtered in a ritual way by a shochet. Pork is forbidden. Fish must have both fins and scales. Thus shellfish, shrimp, and lobster are forbidden. Foods made with milk (milchig) cannot be eaten or mixed with foods that contain meat (fleishig) products. This comes from the biblical injunction that says: “You shall not seethe a kid in its mother’s milk.” Thus, combinations like cheeseburgers are not kosher. All fruits, vegetables, and grains (including pasta) are neither milk nor meat. Such foods are called pareve and may be eaten or mixed with either milk or meat. Eggs are also pareve.If a Jewish homemaker keeps kosher, the kitchen will have two sets of dishes (one milchig, one fleishig), two sets of silverware, two sets of pots and pans, and so forth. When foods are prepared, they are cooked and served with the appropriate utensils. manufactured packaged foods are designated kosher by a heksher on the label.Levels of observance of kashrut and the interpretations of the law vary widely among movements of Judaism and even among families. Some families who keep kosher at home will eat anything when in a restaurant. Some eat only vegetarian dishes or fish in a restaurant to ensure that the food is kosher (even if the tableware is not). Others will only eat in a kosher restaurant that is certified and watched over by a mashgiach. Some persons who keep kosher will eat in another person’s home; some will not unless they are sure the other person also keeps kosher.2. Permissible, proper, or legitimate. Often used when referring to ritual objects such as mezuzot or tefillin that are “correct” according to Jewish law and can be used. “Kosher” may also refer to situations and things outside of Jewish life. For example: “He wants to have a coed sleepover party, but I don’t think that’s kosher.”kosher for Passover The seal of approval (heksher) found on manufactured foods that are pesachdik and contain no leaven, making them acceptable for eating during Pesach.kosher style adj. English Jewish home-style cooking, including favorite foods such as brisket, corned beef, matzah ball soup, kugel, or blintzes. As the name implies, “kosher-style” food is not the same as ritually acceptable kosher food. Although the fare may be similar, the laws of kashrut are not observed in a kosher-style restaurant.

Clean and Unclean Food Leviticus 11     The Lord said to Moses and Aaron, 2 “Say to the Israelites: ‘Of all the animals that live on land, these are the ones you may eat: 3 You may eat any animal that has a split hoof completely divided and that chews the cud. 4 “ ‘There are some that only chew the cud or only have a split hoof, but you must not eat them. The camel, though it chews the cud, does not have a split hoof; it is ceremonially unclean for you. 5 The coney,a though it chews the cud, does not have a split hoof; it is unclean for you. 6 The rabbit, though it chews the cud, does not have a split hoof; it is unclean for you. 7 And the pig, though it has a split hoof completely divided, does not chew the cud; it is unclean for you. 8 You must not eat their meat or touch their carcasses; they are unclean for you. 9 “ ‘Of all the creatures living in the water of the seas and the streams, you may eat any that have fins and scales. 10 But all creatures in the seas or streams that do not have fins and scales—whether among all the swarming things or among all the other living creatures in the water—you are to detest. 11 And since you are to detest them, you must not eat their meat and you must detest their carcasses. 12 Anything living in the water that does not have fins and scales is to be detestable to you. 13 “ ‘These are the birds you are to detest and not eat because they are detestable: the eagle, the vulture, the black vulture, 14 the red kite, any kind of black kite, 15 any kind of raven, 16 the horned owl, the screech owl, the gull, any kind of hawk, 17 the little owl, the cormorant, the great owl, 18 the white owl, the desert owl, the osprey, 19 the stork, any kind of heron, the hoopoe and the bat.b20 “ ‘All flying insects that walk on all fours are to be detestable to you. 21 There are, however, some winged creatures that walk on all fours that you may eat: those that have jointed legs for hopping on the ground. 22 Of these you may eat any kind of locust, katydid, cricket or grasshopper. 23 But all other winged creatures that have four legs you are to detest. 24 “ ‘You will make yourselves unclean by these; whoever touches their carcasses will be unclean till evening. 25 Whoever picks up one of their carcasses must wash his clothes, and he will be unclean till evening. 26 “ ‘Every animal that has a split hoof not completely divided or that does not chew the cud is unclean for you; whoever touches the carcass of any of them will be unclean. 27 Of all the animals that walk on all fours, those that walk on their paws are unclean for you; whoever touches their carcasses will be unclean till evening. 28 Anyone who picks up their carcasses must wash his clothes, and he will be unclean till evening. They are unclean for you. 29 “ ‘Of the animals that move about on the ground, these are unclean for you: the weasel, the rat, any kind of great lizard, 30 the gecko, the monitor lizard, the wall lizard, the skink and the chameleon. 31 Of all those that move along the ground, these are unclean for you. Whoever touches them when they are dead will be unclean till evening. 32 When one of them dies and falls on something, that article, whatever its use, will be unclean, whether it is made of wood, cloth, hide or sackcloth. Put it in water; it will be unclean till evening, and then it will be clean. 33 If one of them falls into a clay pot, everything in it will be unclean, and you must break the pot. 34 Any food that could be eaten but has water on it from such a pot is unclean, and any liquid that could be drunk from it is unclean. 35 Anything that one of their carcasses falls on becomes unclean; an oven or cooking pot must be broken up. They are unclean, and you are to regard them as unclean. 36 A spring, however, or a cistern for collecting water remains clean, but anyone who touches one of these carcasses is unclean. 37 If a carcass falls on any seeds that are to be planted, they remain clean. 38 But if water has been put on the seed and a carcass falls on it, it is unclean for you. 39 “ ‘If an animal that you are allowed to eat dies, anyone who touches the carcass will be unclean till evening. 40 Anyone who eats some of the carcass must wash his clothes, and he will be unclean till evening. Anyone who picks up the carcass must wash his clothes, and he will be unclean till evening. 41 “ ‘Every creature that moves about on the ground is detestable; it is not to be eaten. 42 You are not to eat any creature that moves about on the ground, whether it moves on its belly or walks on all fours or on many feet; it is detestable. 43 Do not defile yourselves by any of these creatures. Do not make yourselves unclean by means of them or be made unclean by them. 44 I am the Lord your God; consecrate yourselves and be holy, because I am holy. Do not make yourselves unclean by any creature that moves about on the ground. 45 I am the Lord who brought you up out of

Egypt to be your God; therefore be holy, because I am holy. 46 “ ‘These are the regulations concerning animals, birds, every living thing that moves in the water and every creature that moves about on the ground. 47 You must distinguish between the unclean and the clean, between living creatures that may be eaten and those that may not be eaten.’ ” [3]  Below is a list from the 613 Commandments of Rambam (Maimonidies) Book of Holiness

Dietary Laws (Kashrut; כַּשׁרוּת)

According to the dietary laws, all fruits and vegetables are permitted, based on the verse, “See, I give you every seed-bearing plant that is upon all the earth, and every tree that has seed-bearing fruit; they shall be yours for food” (Gen. 1:29). In fact, this verse and the subsequent one imply that vegetarianism was the earliest biblical ideal.

Characteristics of Jewish CookingThe two main categories of Jewish cooking may be broadly classified as Sephardic (originating from around the Mediterranean in the Middle East and North Africa and extending to

Asia) and Ashkenazic (of more Western and Northern European origin). A major dividing line was the mountains separating the north and south of Europe, extending from the Caucasus to the

Pyrenees. Over the centuries, the significant Jewish migrations between east and west, rather than north and south, accentuated the differences between Sephardim (who for years tended to live a more cosmopolitan life under Islamic rule) and Ashkenazim (who had a more rural existence and suffered frequent persecutions under Christian domination). The differences in the two styles of cooking are closely related to the climate, soil, and locally available produce. In general, Ashkenazim inhabit a cold world of beef and bland vegetables (cabbage, carrots, potatoes), freshwater fish (especially carp), and salt herring, in which the flavor is brought out by fats, sugar, and onions. In contrast, the world of the Sephardim “is a warm one of peppers and eggplant, zucchini and tomatoes” and features a “sensual, aromatic, and colorful” cuisine that focuses on herbs and spices, olive oil, rice, cracked wheat, beans, lamb, and saltwater fish.

Only in the time of Noah did God allow humans to be carnivorous (Gen. 9:3). God did give Noah one restriction—the consumption of blood was prohibited—but the full set of dietary laws was commanded to the Israelites after they left Egypt, and was further embellished and explicated by the Rabbis. The Jewish dietary laws (derived largely from Lev. 11:1–43) detail which animals, birds, and fish may be eaten; how they are to be slaughtered and prepared; and the rules concerning the separation of meat and milk. 

Beasts

The Bible divides the “beasts of the earth” into those animals that are permitted for consumption (tahor; clean) and those that are prohibited (tamei; unclean). This is based on God’s command that Noah take seven pairs of every clean beast and two pairs of all unclean animals into the ark (Gen. 7:2), a difference that presumably related to the former group being suitable for sacrifice.To qualify as kosher, a quadruped must both chew the cud (ruminant) and have completely cloven (divided) hooves (Lev. 11:3; Deut. 14:6), meaning that they cannot hold prey and thus are not carnivores. The Torah specifies 10 herbivorous animals (wild and domestic) that meet these criteria: ox, sheep, goat, deer, gazelle, roebuck, wild goat, ibex, antelope, and mountain sheep (Deut. 14:4–5). The camel, hare, and hyrax chew their cud but are forbidden because they have incompletely split hooves; the pig has a completely cloven hoof but is prohibited because it does not chew its cud (Deut. 14:7–8). 

Birds

Although kosher quadrupeds and fish are mentioned by characteristics so that their identities are clear, the Torah specifically names 20 non-kosher species of birds, thus implying that all others are kosher (Lev. 11:13–19; Deut 14:11–18). The forbidden birds include osprey, kite, vulture, raven, falcon, and hawk. Unfortunately, over time the precise identities of some of the biblically prohibited birds became unclear. Consequently, the Shulchan Arukh ruled that it is forbidden to eat any species of bird (or its eggs; see p. 707) unless there is a well-established tradition that it is kosher (YD 82:2).1 These include chicken, capon, Cornish hen, domestic duck and goose, pigeon, partridge, and peacock. In general, all birds of prey and scavengers that eat carrion are prohibited (Hul. 59a). According to Nachmanides, all unclean birds are in some degree cruel, so that one who eats their flesh becomes exposed to the danger of acquiring the same characteristic.2 The Mishnah states, “Every bird that has an extra toe [talon], a crop [pouched enlargement of the gullet that stores food], and a gizzard that can be peeled [inner lining that can easily be separated from the outside muscular portion] is clean” (Hul. 3:6; 59a). Nevertheless, in regard to certain birds, such as pheasant, quail, and even turkey, there is a difference of tradition, with some communities regarding them as permitted and others deeming them forbidden.The Rabbis discussed whether the white stork (hasidah) was a kosher bird. According to the Talmud, its Hebrew name (lit., “pious bird”) reflects that “it shows kindness [hasidut] to its companions [i.e., by sharing food with other members of its species]” (Hul. 63a). Nevertheless, the white stork is still considered a nonkosher bird because it shows such compassion only toward its own kind and not to other species, a behavior that was scorned by the sages.3 

Fish

Of “all that live in water,” only those that have fins (snapir) and scales (kaskeset) are “clean” and permitted as food (Lev. 11:9–12). The scales must be capable of being scraped off easily with a knife (Nachmanides), which excludes creatures with scales that are not clearly defined, such as shellfish, shark, catfish, and amphibians.4 Nachmanides explained that fish with fins and scales can swim close to the surface, so that occasionally they come up for air. This warms their blood and enables them to rid their bodies of excess fluids and other impurities. In contrast, those lacking fins and scales keep close to the bottom of the sea, cannot purify their bodies, and thus would be harmful to human health if eaten.5Jews are also forbidden to eat from “among all the swarming things of the water and among all the other living creatures that are in the water” (Lev. 11:10); this prohibits small aquatic creatures and large water animals that are not fish (such as seals, dolphins, sharks, and whales).6  A major controversy concerns the status of swordfish, which has scales when young but then loses them as it gets older. Swordfish is permitted by the American Conservative movement but forbidden by most Orthodox authorities.  InsectsThe Torah specifically permits the eating of four kinds of locusts (Lev. 11:21–22), but because none can be unequivocally identified, later rabbis declared all species of insects to be forbidden. The prohibition against “all winged swarming things” (Deut. 14:19) includes flies, bees, hornets, and similar insects. An exception is the product of an insect that is not part of its body, such as honey from bees (Bek. 7b).  Unlike milk from a cow, honey is a product of the flower nectar that bees gather and then convert into honey. The ban on “all the things that swarm upon the earth” (Lev. 11:41) forbids the eating of worms, beetles, snakes, scorpions, and lizards, which Rashi defined as being low, having short legs, and appearing to creep along the ground.7 Shechitah (שְׁחִיטָה)

The law of ritual slaughtering is derived from the verse, “you may slaughter any of the cattle or sheep … as I have instructed you” (Deut. 12:21). The Rabbis interpreted this to imply that Moses had previously taught the people a method of slaughtering animals. However, since the precise details are not mentioned in the Torah, it follows that the Jewish method of ritual slaughter must have been communicated as part of the Oral Law. Today, the complex and minute regulations dealing with ritual slaughtering must be carried out by a licensed shochet, who in addition to being a skilled professional must be a pious individual who is well trained in Jewish law.Jewish ritual slaughtering strives to prevent unnecessary suffering to the animal. It requires one continuous deep horizontal cut with a perfectly sharp blade with no nicks or unevenness. This severs the windpipe and all of the great blood vessels of the neck so that the animal instantly loses all sensation. Because an animal may not be eaten if it has not been properly slaughtered, the technical requirements must be strictly observed.In addition to slaughtering the animal, the shochet must also carry out a detailed examination (bedikah) of the carcass. Any defect of the major organs renders the animal treif and forbidden for consumption. Initially referring to the flesh of an animal torn by a wild beast or wild bird, the word “terefah” was later applied to the flesh of any injured or diseased animal that would not have lived for more than a year (Hul. 3:1). Eventually, treif became the generic term for any product that was not kosher, and thus not ritually fit for Jewish consumption. The halakhah permits certain abnormalities in the lungs that have been determined to be harmless. However, those Jews who are strictest in their observance of kashrut eat only glatt kosher meat—a term that is derived from the Yiddish word for “smooth” and refers to animals with smooth, lesion-free lungs.8Shechitah and bedikah of poultry are carried out in the same careful manner, though only the intestines are examined. There are no specific regulations about how fish are to be killed. After shechitah, the animal is suspended head down to drain as much blood as possible from the body.Jewish law prohibits eating the flesh of any kosher animal that has died without kosher slaughter. Termed “nevelah,” this includes not only an animal that died a natural death but also one that has been killed by hunting or was not correctly slaughtered. Unlike the nonkosher creatures that the Torah terms “abomination,” nevelah is permitted to gentiles; according to Sforno,9  it is forbidden to Jews only because it is not appropriate food for a holy people.10 Although Abravanel11 deemed nevelah to be reprehensible to God because it was a pagan custom to eat of this particular kind of meat,12 Rabbi Meir13 stated that the owner of the carcass had the right to benefit from it by selling it to a gentile, even though it could not be eaten by a Jew  

Preparation of Meat (Kashering)

The unequivocal biblical prohibition against the consumption of blood is the basis for the process of kashering meat (Lev. 7:26–27, 17:10–14). This is the only dietary law for which the Torah provides a reason: “For the life of the flesh is in the blood, and I have assigned it to you for making expiation for your lives upon the altar.” Therefore, before meat is cooked, it is necessary to remove all traces of blood—by soaking and salting the meat or by broiling or roasting it over an open flame.After being washed to remove all externally visible blood, the meat is placed in a large container and covered completely in lukewarm water for a half hour so that it softens and will absorb salt. The meat is then placed on a flat slatted board through which blood can drip or on a sloped board so that the blood can drain off into a sink or empty container. It is salted thoroughly on all sides and left on the board for one hour. Coarse (kosher) salt is used because of its effectiveness in drawing out the blood from the meat. After being rinsed off several times, the meat is considered in proper condition for cooking. This entire process must be completed within 72 hours after ritual slaughter; otherwise, the blood is considered to have congealed inside the meat, which must then be broiled or roasted over an open flame before it can be eaten.15Meat that is to be broiled does not need to be kashered, since the broiling process drains off at least as much blood as is removed by soaking and salting. Nevertheless, some people still sprinkle salt on meat before broiling. Salting is not considered effective enough to kasher the blood-saturated liver, which must first be broiled on a rack to allow the juices to drain before being further cooked in whatever way desired.16 

Forbidden Portions of Kosher Animals

The sciatic nerve and its associated blood vessels must be removed before the hindquarters of any “beast” can be prepared for consumption. This nerve extends from the rear of the spinal column and runs down the inner side of the leg. Although some expert butchers can perform the difficult task of cutting out the sciatic nerve, in general the process is so time-consuming and costly that many kosher butchers do not handle the hindquarter at all. Packinghouses usually sell the hindquarters of kosher-slaughtered animals to the general market for nonkosher cuts of meat such as sirloin or T-bone steak and filet mignon.17The prohibition against eating the sciatic nerve is an eternal reminder of the wrestling match between Jacob and the “stranger,” which took place as the Patriarch was returning to the Land of

Israel after dwelling 20 years with his father-in-law, Laban (Gen. 32:25–32). During this titanic struggle—which resulted in Jacob’s name being changed to

Israel, since he had “struggled with God”—the attacker injured Jacob’s thigh, resulting in a residual limp. Sefer ha-Hinnukh maintained that this commandment is a symbol of

Israel’s survival; just as Jacob faced a daunting task yet emerged victorious, so Jews throughout the ages should have confidence in God’s assistance in helping them overcome the fiercest attacks of their enemies. Sforno viewed the commandment as symbolically teaching Jews that physical handicaps should not discourage their fight for survival.
18
The fat portions (chelev) surrounding the kidneys, liver, stomach, and intestines, which were sacrificed on the altar in biblical and

Temple times, are also forbidden for consumption (Lev. 7:23). This prohibition applies to the abdominal fat of oxen, sheep, and goats, unless it is covered by flesh; however, it was permitted to eat the fat (shemen) of the deer, hart, and other kosher wild animals that could not be used for sacrificial offerings. Abravanel wrote that eating chelev could lead one to become fat and lose the ability to function physically or mentally. Recanati maintained that fats were forbidden as food because they were included in animal sacrifices and thus were considered sacred.
19

 Mixing Milk and MeatThe prohibition against mixing milk and meat derives from the verse, “You shall not boil a kid in its mother’s milk” (Exod. 23:19, 34:26; Deut. 14:21). Since it became impossible to determine which baby goat and which mother’s milk were related, the law was extended so that no animal (meat) could be cooked in any milk (dairy). The Rabbis interpreted the threefold repetition of this verse as defining three separate prohibitions: cooking meat and milk together, eating such a mixture, and deriving any benefit from it (such as savoring the aroma or feeding it to a pet) (Hul. 115b). The term “milk” was interpreted to mean all dairy products, such as butter, cheese, and fresh and sour cream. Because many commonly eaten processed foods contain unsuspected dairy ingredients—such as bread, cakes, and cookies made with buttermilk, nonfat dry milk, whey, or dairy-derived additives—kashrut observers always read the labels carefully and buy products only with a hechsher (kosher certification).Those Jews who are strictest about their observance of kashrut have special requirements for the dairy products they eat, consuming only those labeled chalav Yisrael (milk of the Jewish people). In addition to making certain of the standard requirement that all milk and dairy products never come into contact with any meat or meat products, the most rigorous insist that cows be closely watched to ensure that they never eat any nonkosher food or have their milk mixed with any that is not kosher.

Kashrut CertificationKeeping kosher has become much easier in recent years, since at least 75% of prepackaged products (and most major brands) now have some type of kosher certification indicated by a hechsher. Coming from the same Hebrew root as the word “kosher,” a hechsher is effectively a symbol indicating that the product has been certified as kosher by a specific rabbi or organization. In addition to the kashrut symbol, many kosher certifying organizations add the letter “D” (or the word “dairy”) or “M” (or the word “meat”) as appropriate. For pareve (neither milk nor meat) products, the word itself is added, since the letter “P” is used to indicate that a product is kosher for Passover. In the absence of such clarifying words or letters, it is essential to read the list of ingredients carefully to determine whether the product is meat, dairy, or pareve.1“Kosher-style” is a meaningless term, since a product is either kosher or not kosher. Indeed, the term is highly misleading since it “tends to confer credibility upon merchants doing business in the Jewish community by attaching a quasi-religious label to their wares, when in fact no kosher status exists.” It is important to remember that so-called Jewish foods—such as challah, gefilte fish, blintzes, kugel, latkes, and even chicken soup—are not inherently kosher. Even though they are associated with Jewish traditions, these items must still be prepared from kosher ingredients according to the dietary laws.2

The production of cheese is also tightly regulated. Most hard cheeses require that the milk be curdled or coagulated in rennet, the inner lining of the stomach of a calf. To be strictly kosher, the rennet must come from a kosher animal that was slaughtered in a ritually correct manner and whose stomach was correctly prepared and thoroughly dried. Conservative halakhic interpretation permits all hard cheeses. Today, cheese can be made using vegetable enzymes.20In order to create a “fence around the Torah,” the Rabbis decreed that the separation of meat from milk must be as complete as possible. Thus it is necessary to use separate utensils (pots, pans, dishes, and flatware) for dairy foods and meat (known in Yiddish as milchig and fleishig, respectively). This entails storing the utensils in separate areas, washing them in separate bowls or sinks, and drying them with different dishcloths (ideally of distinct colors to prevent any mistake). When using a dishwasher, it is necessary to have separate dish racks; if these are not available, the dishwasher must be run through a cycle between meat and dairy loads.Because meat takes a long time to digest, or due to residual meat particles or fatty residues caught in the teeth or their taste remaining on the palate, Jewish law rules that one must wait a designated period after eating a meat meal before ingesting milk products. Customs range from an hour for Jews of Dutch ancestry to three hours for German Jews and six hours for those from other European countries. The waiting time between milk and meat is much shorter. One is generally permitted to eat meat almost immediately after a milk meal, after thoroughly rinsing the mouth and eating a piece of bread or some other “neutral” solid. After hard cheese, however, it is customary to wait a longer period (up to six hours in some traditions) before eating meat.Today, there is wide availability of imitation milk derived from soybeans, coconuts, almonds, rice, and oats that may be used with meat. Fruit, vegetables, grains, and eggs are all considered neutral (pareve) and may be eaten together with milk or meat dishes. Fish is also a neutral food, but the Rabbis traditionally prohibited cooking or eating fish and meat together because they were convinced that this mixture was dangerous for one’s health. Today, there is a difference of opinion on the subject of eating meat and fish together.Maimonides viewed the prohibition against mixing meat and milk as an attack on idolatry and superstition.21  He argued that combining meat and milk was a pagan custom and thus not appropriate for Jews. Abravanel and Luzzatto maintained that it was a humanitarian ordinance to discourage a practice that would tend to harden the heart.22 Ibn Ezra argued that it would be the “act of a cruel heart” to take milk, a substance that the Creator made to nourish life, and use it in a manner designed to destroy that life.23 

Rationales for the Dietary Laws

Many attempts have been made to explain the dietary laws. The Bible defines them as hukim, divine statutes that by definition are not explained in the text. However, the underlying rationale for the laws of kashrut is stated in the verse, “You shall sanctify yourselves and be holy, for I [your God] am holy” (Lev. 11:44). This commandment has two aspects: the positive aspect of imitating God by manifesting such divine traits as being merciful and loving, and the negative aspect of withdrawing from things that are impure and abominable. Thus Jews were required to avoid anything that could defile them, either physically or spiritually.24  The consumption of nonkosher food impedes people’s ability to elevate and sanctify themselves, dulling their spiritual potential and creating a barrier between Jews and their perceptions of holiness.Maimonides noted that “the dietary laws train us in the mastery over our appetites; they accustom us to restrain both the growth of desire and the disposition to consider the pleasure of eating and drinking as the end of man’s existence.”25 This concept is illustrated in the Sifra (11:22), a halakhic midrash on Leviticus, which states: “Let not a man say, ‘I do not like the flesh of swine.’ On the contrary, he should say, ‘I like it but must abstain, seeing  that the Torah has forbidden it.’ ”Effects on the SoulFor Ezekiel (33:25), the eating of blood was equivalent to the sins of idolatry and murder. Conversely, abstaining from this practice decreases the innate human instinct for violence. The Zohar extended this to all forbidden food, noting that the consuming of blood and the worshiping of idols are both referred to as “abominations.” The prohibition of birds of prey, which survive by their ability to kill other creatures, is a moral injunction against taking advantage of one another, for such predatory behavior is out of character with the Jewish attitudes of compassion and mercy.26 For Ibn Ezra, the prohibition against aesthetically repulsive animals (such as eels, roaches, and ants) was simply that it would be impossible for one to have a pure, clean conscience with the knowledge that his own flesh is the product of a diet of insects, snakes, and other vermin. In his allegorical Torah commentary, Akedat Yitzhak,27 Isaac ben Moses Arama (15th century) wrote: “The reason behind all the dietary prohibitions is not that any harm may be caused to the body, but that these foods defile and pollute the soul and blunt the intellectual powers, thus leading to confused opinions and a lust for perverse and brutish appetites that lead men to destruction, thus defeating the purpose of Creation.” 

Effects on the Body

As a physician, Maimonides observed, “All food that is forbidden by the Law is unwholesome.”28 Sefer ha-Hinnukh noted that “the injurious effect of some forbidden foods in not known to us, or even to physicians. The True Faithful Doctor who has commanded us in all these things is infinitely wiser than we. How petty and foolish is the man who thinks that only those things which his understanding grasps are true, and everything else, everything unknown to him, is not true.”29  Maimonides maintained that the reason for the injunction against the consumption of sacrificial fat (chelev) was that “it fattens and destroys the abdomen and creates cold and clammy blood.”30  Concerning the prohibition of milk and meat, he added, “Meat boiled in milk is undoubtedly gross food, and makes a person feel overfull.”31  Later authorities argued that certain animals (especially nonkosher ones) harbor parasites that spread disease. Indeed, medieval Jews suffered less than their gentile neighbors from the waves of epidemics that decimated the population. 

Separation

The dietary laws preserved the distinction between the Jews and other neighboring peoples (Tob. 1:10–11), as is first told in the story of Joseph, when the Egyptians refuse to eat with their Hebrew visitors (Gen. 43:32). Later, the young Daniel in the Babylonian court “resolved not to defile himself with the king’s food or the wine he drank”; he made do with a spare vegetarian diet (Dan. 1:8, 12). And Judith ate her own food when she dined with a Babylonian general (Judith 12:2). In the Maccabean period, obedience to the dietary laws became such a mark of Jewish loyalty that Jews chose martyrdom rather than eating pig meat.32For the early Rabbis, the secret of Jewish survival was separatism—being a holy people required being a people apart. As expressed in the early Apocryphal Book of Jubilees (22:16): “Separate yourself from the nations, do not eat with them, do not act according to their deeds, and do not associate with them, because their work is uncleanness, all their ways are contamination, detestation and abomination. They slaughter their sacrifices to the dead and pray to demons.”33  By following the dietary laws, the observant Jew may have less opportunity to socialize with non-Jews (since this often entails eating together). According to this view, the observance of kashrut has been a critical factor in decreasing the rates of Jewish assimilation and intermarriage.34 

Conclusion

The general consensus is that the Torah is not a medical textbook and the dietary laws are not primarily designed to preserve bodily health. Rather, as Samuel Dresner wrote:Kashrut demands sacrifice, self-discipline and determination—but what that is really worthwhile in life does not? It demands the courage to turn our face against the powerful current of conformity that almost overcomes us daily. The goal of kashrut is holiness, a holy man and a holy nation. It is part of Judaism’s attempt to hallow the common act of eating, which is an aspect of our animal nature. It likewise sets us apart from the nations. Thus it achieves its objective—holiness—in these two ways, both of which are implied in the Hebrew word kadosh: inner hallowing and outer separateness.”35[4]

Jewish Law – Kashering

 
  • A pot can become not Kosher if it used to cook milk and meat within the same 24 hour period, if it is used to cook non-kosher food, or on Passover, if it was used prior to Passover for Chametz (wheat or barley or any of the 3 additional grains). Flavor from the foods cooked can remain in the walls even after being washed, and it can add flavor to food cooked in the pot afterwards.
     
  • The only time we are required to apply the Koshering Process is on items that are normally used directly on the fire, or are in contact with hot foods that are directly on the fire. These are called Keli Rishon and Iruy Keli Rishon respectively.
     
  • The basic concept of Koshering these pots are to cook with them in the same way to remove any possible edible flavors that may come out of the wall of the pot. Each type of item has a specific process related to its standard use. To determine which process is to be used, we follow its most common use. For example, an item normally used as a Keli Sheni (not directly on the fire),even though a few times you use it as a Keli Rishon (directly on the fire), you treat it as a Keli Sheni and it does not need any Koshering.
     
  • For Ashkenazim only, Koshering is only done after the item and the pot used for Koshering were both not used for the non-kosher food or the Chametz for a 24 hour period. Bedi Avad, (if it was already done) it is kosher anyway. Sephardim will require this only on items that were used for Treif (non-kosher food).
     
  • Hagalah is used for pots, pans, and utensils that are used normally as Keli Rishon or Iruy Keli Rishon. Even though technically Iruy Keli Rishon is a bit less strict than Keli Rishon, it’s simpler to do the same process for both. You take the item and drop it into boiling water and then remove it and put it under cold water. Make sure the entire item gets to the boiling water, even if you need to turn it around and immerse it again. If the item to bekoshered is a pot, you may put enough water into that pot and just steam it up with the cover on, and then put it under the cold water.
     
  • If there was extra caked on food that you cannot remove, which can often build up in cracks by the handle, just put detergent and/or bleach on it to render that food inedible.
     
  • The following is a list of items and the specific Koshering Processes required:
     

    • Metal Pots, Metal pot covers, soup ladles, utensils used in cooking, silverware (Metal), all can be koshered with Hagalah, described above.
       
    • Frying pans, kitchen grills, and barbeque grills can be koshered by putting the fire on it without anything in it, until it gets pretty hot. No need to burn the pan.
       
    • Baking pans can be koshered by putting them in the oven for a half hour on the highest flame.
       
    • Glass, plastic, glazed china, glazed dishes, Corelle, Pyrex, Corningware, or glazed earthenware does not need any Koshering for Passover, since they do not retain any flavor.
       
    • Ovens, toaster ovens, and convection ovens can be koshered by putting them on the highest flame for a half hour. If they have a self-cleaning option, running the self-cleaning process is certainly good.
       
    • Warming drawers do not need to be koshered if they do not normally exceed 125 degrees Fahrenheit.
       
    • Microwave Ovens can be koshered by putting a bowl of water on the highest setting for twenty minutes.
       
    • Keli Cheres (clay type pots, similar to some flower pots) that are not glazed cannot be koshered, because the flavor it retains cannot be removed.
       
    • Sinks, refrigerators, trash cans, counters, dishwashers, stovetops, tables, cutting boards, mixmasters, silver kiddush cups, and anything not used with hot foods from the fire do not need any koshering.
 

[5] So what are our responsibilities today, as far as keeping “Kosher”?  It is very simple in fact.  G-d commands that His people be holy( Lev. 11:44), and He gives the guidelines for holiness(Deuteronomy 28:9-14).  By eating only the clean foods, and refraining from the unclean foods, one is in alignment with the will of G-d( Lev 11).  Now there are arguments from a Christian standpoint, that Yeshua rendered “all foods” as clean. And they cite Mark 7:1 as their proof.  However, Yeshua was a righteous Jew.  He had to keep all of the commandments and keep them correctly in order to be “the lamb without blemish”.  He would have never seen the unclean animals listed in the Torah, Leviticus 11, as food.  And Mark 7 is Yeshua speaking of the “tradition” of ritual washing of hands before eating.  Then some will use the argument of the dream of Peter (Acts 10:9-16) yet most don’t go on to read that the dream isn’t speaking of food, but of the Gentiles.  Still others use

Col 2:16-23, as a basis of eating “unclean” food.  However, Paul says the reality is found in the Messiah.  Well, if that is so, what did Yeshua do?  He certainly kept Biblical Kosher.  He had to, he was the living Torah.  Now the rabbis, and sages have built many “hedges” of protection around the kosher laws, and that is all well and good for those who wish to follow, as long as it doesn’t conflict with the Torah.  The final argument, would be Colossians 2:14, where Paul states,  4 having canceled the written code, with its regulations, that was against us and that stood opposed to us; he took it away, nailing it to the cross.[6]   The written code is interpreted as Torah.  If this is true then that totally is opposed to what Yeshua says in Matthew 5:17-20,  The Fulfillment of the Law17 “Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them. 18 I tell you the truth, until heaven and earth disappear, not the smallest letter, not the least stroke of a pen; will by any means disappear from the Law until everything is accomplished. 19 Anyone who breaks one of the least of these commandments and teaches others to do the same will be called least in the kingdom of heaven, but whoever practices and teaches these commands will be called great in the kingdom of heaven. 20 For I tell you that unless your righteousness surpasses that of the Pharisees and the teachers of the law, you will certainly not enter the kingdom of heaven. [7]   Yeshua also stated in Matthew 23:1-3: 23          Then Jesus said to the crowds and to his disciples: 2 “The teachers of the law and the Pharisees sit in Moses’ seat. 3 So you must obey them and do everything they tell you. But do not do what they do, for they do not practice what they preach.[8]  What is Yeshua saying here?  It seems pretty clear, we should do as they teach but with the right intentions.  Now there is a quite new viewpoint from this passage.  Nehemiah Gordon, a Karaite Jew, says that in a Hebrew copy of the book of Matthew, says that where in most versions it translates as “,they  and them” in verse 3, in the Hebrew it translates as he referring to Moses.  That implies Yeshua is saying that we should obey the Law of Moses. So it seems pretty clear that Yeshua did not abolish the Law or the Prophets.  So what is Paul saying, is he in opposition with the teaching of Yeshua?  You have to know who Paul is talking to.  He is speaking to Gentile believers in Yeshua.  Gentile believers would not have been held to the same “kosher” restrictions as Jews, but only to the seven Noahide Laws.  In Acts 15, Peter and the

Jerusalem Council were discussing what should be done with all the Gentile believers.  Acts 15:19-21 tells of their decision.

 19 “It is my judgment, therefore, that we should not make it difficult for the Gentiles who are turning to God. 20 Instead we should write to them, telling them to abstain from food polluted by idols, from sexual immorality, from the meat of strangled animals and from blood. 21 For Moses has been preached in every city from the earliest times and is read in the synagogues on every Sabbath.”  Look closely at v.21.  Here, it implies that the Gentile believers will go and hear the “law of Moses” in the synagogues every Sabbath.  This also implies that the early “Church” would be keeping the Sabbath, but that is for another study.  Here, Peter is saying that through hearing the Torah in the Synagogues every Sabbath, a Gentile believer, would soon learn the “mitzvot” or commandments.  It doesn’t support the belief, in any way that Yeshua, “abolished” the law.  Paul isn’t clear with the intentions of his teaching.  Unfortunately, we don’t know what issues the Colossian believers were having; we have only the response of Paul.  However, he may have assumed that as new believers in Yeshua, as they did in Acts, he was not going to make it difficult, for the believers, of course there isn’t any proof, it’s just a theory. In any event Paul isn’t the Messiah, Yeshua is.  And as believers we should follow by his example, for it is the perfect example, not Paul’s, Peter’s, James’, John’s etc.  I know that may seem as heresy to some.  But think about it.  Who is our example?  Who was the lamb without blemish?  Who?  Yeshua, that’s who.  The rest are imperfect men, just as we are.  Therefore, knowing that Yeshua, would have followed the Torah perfectly, and we being followers of him, shouldn’t we do the same.  He commands that we do.  But Paul is a Pharisee; he claims that he still is Acts 26:5, and Philippians 3:5.   [9] 17 “Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them. 18 I tell you the truth, until heaven and earth disappear, not the smallest letter, not the least stroke of a pen; will by any means disappear from the Law until everything is accomplished. 19 Anyone who breaks one of the least of these commandments and teaches others to do the same will be called least in the kingdom of heaven, but whoever practices and teaches these commands will be called great in the kingdom of heaven. 20 For I tell you that unless your righteousness surpasses that of the Pharisees and the teachers of the law, you will certainly not enter the kingdom of heaven. [10]

Another point might be made in why we should follow the Torah commands about keeping kosher.  Jews and Christians alike believe that our bodies are created in the image of G-d, so why would we defile that image with something that G-d has called unclean.  Some see their bodies similar to the Temple, where the Spirit of G-d resides.  During the

Second

Temple, a Greek ruler named Antiochus Epiphanies attacked the Jews and desecrated G-d’s holy

Temple.  One thing he did was sacrifice a pig on the altar.  This is known as the abomination that causes desolation.  If you see your own body as a mini-Temple, why would you put things in it that G-d has called unclean, and abominable?  Because some “early church father” or “humanistic rabbi” says it’s okay now.  Ecclesiastes says there is nothing new under the sun and it rings so true.  Man has always and continues to try to justify not obeying G-d.  We have come with terms like “legalism” and “enlightenment” to disregard the fundamental truths of G-d’s word to us.  

 Some more liberal Jews don’t keep Kosher, because it doesn’t make sense today.  Reform Judaism actually rejected kosher laws earlier in the movement as well as keeping the Sabbath on Sunday.  However, a lot of Reform or liberal Jews keep some form of Kashrut today.  Such as No mixing milk and meat, only kosher meat or vegetarianism.   The past sages of Judaism and a lot if not most rabbi’s today would say, gentiles are not expected to keep the dietary laws.  I don’t agree.  The Torah is for all nations.  The Jews are the light to the nations (Isaiah 42:6)   6 Observe them(laws) carefully, for this will show your wisdom and understanding to the nations, who will hear about all these decrees and say, “Surely this great nation is a wise and understanding people.” Deuteronomy 4:6 

Is G-d a liar? Does He not know what is best for us?  Did He not create us?  Why then must we act as rebellious children and not do as He asks?  When Yeshua, returns, and during the messianic age, what do you think will happen?  Will he not keep the Sabbath, will he not be at the

Temple, and will he not obey the Torah?  Will he not still be Jewish? Is he not the living Torah?

 So Jews of course should keep Kosher, but what about Christians?  If you seek the truth you will find, that Yeshua, did, and if you truly follow him, then you will see that the Torah is not abolished, that is a falsehood.  G-d says we should be a holy people, remember, as Christians, you were grafted into the root, and you didn’t replace it (Romans 11).  I know that may hard to hear for some, but the truth is the truth, G-d said it, Yeshua did it, why shouldn’t we obey? Overview: Biblical Kosher:  Leviticus 11; Deuteronomy 14:3-21  Rabbinical Kosher:  Includes all biblical Kosher as well as Talmudic views on interpretations, such as mixing milk and meat, and koshering kitchens and utensils. 

We all have room for improvement in our lives.  The ultimate goal is to draw nearer to G-d in everything that we do.  He gives us direction on just how to accomplish this.  He also, allows us to go down our own paths.  Somehow, our own paths are more confusing and get us lost, and it takes much longer to draw near to Him.  We see it as a short cut, but in the end its foolishness (1 Corinthians 1:25).
