1. Understanding Kosher: A Detailed Exploration
Kosher, derived from the Hebrew word meaning “fit” or “proper,” denotes adherence to Jewish dietary laws, known as kashrut. These laws govern which foods are permissible to eat and how they must be prepared and processed. Rooted in the Torah (Leviticus 11 and Deuteronomy 17), these guidelines have been interpreted and applied over millennia by rabbinic scholars, with additional protective measures enacted to ensure their integrity.
1.1 Who Needs to Understand Kosher?
Understanding what does kosher mean and its implications is crucial for a diverse group of people, including:
- Individuals following a kosher diet: Those who adhere to kosher laws for religious or cultural reasons need a comprehensive understanding of these regulations.
- Food manufacturers and producers: Companies seeking kosher certification must understand and comply with these standards to ensure their products meet kosher requirements.
- Consumers with dietary restrictions: Individuals with allergies or specific dietary needs may find kosher products a reliable option due to stringent production standards.
- Anyone curious about Jewish culture: Learning about kosher laws offers insights into Jewish traditions, values, and practices.
1.2 The Foundations of Kashrut
The basis of kashrut resides in the Torah, specifically in the books of Leviticus and Deuteronomy. These texts lay out the fundamental rules regarding permitted and forbidden foods. Over centuries, rabbinic scholars have interpreted these laws to apply them to modern situations. Additional regulations were also introduced to safeguard the kosher laws.
1.3 The Essence of Kosher
While some may attribute hygienic benefits to keeping kosher, its primary purpose is to follow God’s will, as outlined in the Torah. Observance of kashrut is about spiritual adherence and following religious principles.
1.4 From Kitchen to Industry
In the past, determining if a product was kosher was easy. Foods were typically made at home or in small local businesses. If rabbinical supervision was needed, the local rabbi, known to everyone, provided it. However, today’s mass production and global shipping mean many foods are processed in factories far away. This makes it hard to know if a product is kosher.
1.5 Decoding Ingredient Declarations
Ingredient declarations are often insufficient to determine whether a product is kosher. Several factors contribute to this challenge:
- Equipment: Kosher ingredients processed on non-kosher equipment can render the final product non-kosher.
- Processing Aids: Certain processing aids, like pan liners and release agents, aren’t required to be listed by the USDA but can affect kosher status.
- Ingredient Variability: Many ingredients, like glycerin and emulsifiers, can be either kosher (vegetable-based) or non-kosher (animal-based).
- Broad Terminology: Ingredients are often listed in broad terms, such as “flavors,” without specifying the complex components they contain.
1.6 Seeking Reliable Certification
The complexities of modern food production make it difficult for the average consumer to assess a product’s kosher status. Therefore, purchasing products with reliable kosher certification from recognized agencies is essential.

2. Kosher Food: Detailed Rules
Kosher food regulations cover meat, poultry, fish, dairy, and other food types. Strict rules govern what is allowed and how it must be prepared.
2.1 Kosher Meat, Poultry, and Fish
The Torah specifies which animals are kosher. Kosher meat and poultry also require special preparation.
2.1.1 Meat
Kosher mammals must chew their cud (ruminants) and have cloven hooves. Examples include addax, antelope, bison, cow, deer, gazelle, giraffe, goat, ibex, and sheep.
2.1.2 Poultry
The Torah lists 24 forbidden bird species, with all others considered kosher. However, only birds with an established tradition of being kosher are eaten. In the United States, this includes chicken, turkey, duck, and goose.
2.1.3 Fish
Kosher fish must have fins and scales that are easily removable without damaging the skin. Shellfish are prohibited. Unlike meat and poultry, fish does not require special preparation. However, visible scales are needed to verify the fish’s kosher status. Filleted or ground fish should only be purchased under supervision or with a skin tab showing scales. Buying fish in a non-kosher store can be problematic due to non-kosher knives and tables.
Fish and meat may not be eaten together but can be served one after the other in the same meal. Different dishes and cutlery should be used for each course. Eating some solid food and drinking water or a beverage in between courses is also recommended. Processed and smoked fish require reliable kosher supervision.
2.2 Meat & Poultry Processing
Special procedures are required to prepare meat and poultry according to kosher laws.
2.2.1 Shechita (Slaughter)
Shechita is the prescribed method of slaughtering meat and poultry. The animal’s trachea and esophagus are cut with a sharp, smooth blade, causing immediate death without pain. Only a trained shochet (kosher slaughterer) can perform shechita.
2.2.2 Bedika (Inspection)
After slaughter, a bodek (inspector) examines the internal organs for abnormalities that may render the animal non-kosher (treif). The lungs are checked for adhesions (sirchot), which could indicate a puncture. This inspection ensures a higher standard of quality than government requirements.
2.2.3 Glatt Kosher
Some communities only eat meat from animals with lungs free of adhesions. “Glatt” means “smooth” and implies that the meat is unquestionably kosher.
2.2.4 Nikkur (Excising)
Nikkur involves removing forbidden blood vessels, nerves, and fat lobes from kosher animal species. Specially trained individuals perform nikkur on beef, veal, and lamb.
2.2.5 Koshering Meat
The Torah prohibits consuming animal blood. “Kashering,” the process of extracting blood, is done by salting or broiling. Meat should not be placed in warm water before kashering, and cooked meat cannot be made kosher.
2.2.5.1 Salting Meat
- Soak the meat for 30 minutes in cool water in a designated utensil.
- Allow excess water to drip off, then thoroughly salt the meat with coarse salt, covering the entire surface. Both sides of meat and poultry must be salted.
- Remove loose inside sections of poultry and soak and salt each part individually.
- If the meat is sliced during salting, soak and salt the newly exposed surfaces.
- Leave the salted meat for an hour on an inclined or perforated surface to allow blood to flow freely. The cavity of the poultry should face downward.
- After salting, thoroughly soak and wash the meat to remove all salt.
Meat must be kashered within 72 hours after slaughter to prevent blood from congealing. Soaking the meat before this limit extends the time to complete salting.
2.2.5.2 Broiling
Broiling is another method for kashering meat. Liver can only be kashered through broiling.
- Wash the liver and meat thoroughly to remove surface blood.
- Salt them slightly on all sides.
- Broil them on a designated liver-broiling perforated grate over an open fire to draw out internal blood.
- Make slits in the liver before broiling.
- Broil the meat or liver on both sides until the outer surface is dry and brown.
- Rinse off the meat or liver after broiling.
2.2.6 The Kosher Butcher
Slaughtering, bedika, nikkur, and salting have shifted to slaughterhouses, ensuring consistent high standards. The kosher butcher distributes the product and must be a person of integrity, with the store under reliable rabbinic supervision.
2.2.7 Packaging
Kosher meat and poultry must be supervised from slaughter to the consumer. A metal tag (plumba) with the kosher symbol or tamper-proof packaging with the kosher logo serves as proof of supervision.
2.2.8 Kosher Costs
Kosher meat and poultry are more expensive due to the labor-intensive processing requirements (shechita, bedika, nikkur, and salting) performed by trained individuals.

3. Kosher Dining Out: Guidelines
Kosher caterers, restaurants, and hotels must be supervised by a reputable Orthodox Rabbinic authority. Assumptions about kashrut should not be made based on advertisements or statements. Vegetarian or dairy restaurants are not automatically kosher and require supervision. Fish, baked goods, cheese, shortening, oil, eggs, margarine, dressings, and condiments need supervision. Even kosher raw ingredients can become non-kosher if prepared on non-kosher equipment.
4. Meat and Milk in the Kosher Kitchen
The Torah prohibits cooking, eating, or deriving benefit from meat and milk together. This prohibition extends to not eating meat and dairy at the same meal or preparing them on the same utensils. Milk products cannot be consumed after meat for a period of time, typically six hours. Meat may be eaten after dairy products, except for hard cheese aged six months or more, which requires the same waiting time. Before eating meat after dairy, one must eat a solid food, drink a liquid, or rinse one’s mouth and check the cleanliness of hands.
4.1 Utensils
A kosher kitchen must have two sets of utensils: one for meat and poultry and one for dairy foods. This includes separate pots, pans, plates, and silverware.
4.2 Washing Dishes
Ideally, a kosher kitchen has two sinks, one for meat and one for dairy. If this is not possible, dishes and utensils should be washed on a rack to avoid touching the sink. Separate racks should be used for meat and dairy. Water should not reach the level of the rack, and dishes cannot be soaked in a sink used for both dairy and meat.
5. Eggs
Eggs from non-kosher birds or fish are not kosher. Caviar must come from kosher fish and requires supervision. Commercial liquid eggs also need supervision. Eggs with blood spots should be discarded.
6. Shortening and Oil
Labels must specify the type of shortening (vegetable or animal) and its source. Even pure vegetable shortening requires kosher certification because manufacturers often process animal fats on common equipment.
7. Emulsifiers
Emulsifiers are used in many food products and can be produced from animal or vegetable oil. They require reliable kosher supervision. Common emulsifiers include polysorbates, glycerides, mono and diglycerides, and sorbitan monostearates.
8. Flavors
Flavors, whether artificial or natural, are components of nearly every product and use raw materials from various sources. Kosher-sensitive ingredients in flavors include fusel oil, glycerin, and castorium. Food items containing natural or artificial flavors require reliable supervision.
9. Fillings and Cremes
All fillings, cremes, and fudge bases must be certified kosher because they may contain fats, emulsifiers, gelatin stabilizers, and flavors.
10. Breads, Rolls, Challah, Bagels, and Bialys
These staples present kosher problems and require kosher certification. Many breads contain oils and shortenings. Pans and troughs in bakeries are coated with grease or divider oils, which may be non-kosher and not listed on the label. There may also be non-kosher products prepared on the same equipment.
Producing bread with dairy ingredients is prohibited. Exceptions include bread baked in an unusual shape indicating it is dairy or a loaf so small it would be consumed at one meal.
Jewish law requires setting aside a portion of batter or baked product for “challah.” This ritual is obligatory when the owner of the dough is Jewish, and the dough is made from wheat, oats, rye, spelt, or barley. There is no requirement to separate challah if the batter contains less than 2-1/2 pounds of flour. If the batter contains at least 5 pounds of flour, a blessing is recited before separating challah. If this mitzvah has not been performed in the bakery, it may be done at home.
11. Cake, Pastries, and Doughnuts
These products typically contain shortening, emulsifiers, flavors, and other kosher-sensitive ingredients, necessitating reliable supervision.
12. Dairy Products
Dairy products have specific kosher requirements.
12.1 Milk
Rabbinic law requires supervision during milking to ensure the source is a kosher animal. The OU policy follows the opinion that USDA regulations in the United States are sufficient to ensure only cow’s milk is sold commercially, fulfilling the rabbinical requirement for supervision. Some individuals only consume milk produced with full-time supervision, known as cholov yisroel.
12.2 Cheese
All cheeses require kosher certification, including hard and soft cheeses. Hard cheese often uses rennet, processed from the stomachs of unweaned calves, as a curdling agent. Kosher hard cheese is produced with microbial rennet derived from kosher sources. Even when animal rennet is not used, a full-time supervisor must be present to guarantee the product’s kosher integrity. Hard cheese produced with kosher ingredients and a full-time supervisor is known as gevinat yisroel. Soft cheeses may contain non-kosher cultures and flavors. Since these products are pasteurized, the equipment’s integrity is also an issue.
13. Pareve Foods
“Pareve” means the food item contains no dairy or meat ingredients and was not processed with heat on dairy or meat equipment. Pareve foods are neutral and can be eaten with meat or dairy.
13.1 Labeling
OU policy is that dairy or meat items are labeled OU-D and OU Dairy or OU Meat, respectively. An item labeled OU without a suffix can be assumed to be pareve. However, checking the ingredient list is recommended.
13.2 Sherbets
Products labeled “sherbet” or “fruit sherbet” must contain milk and are not pareve. Water ices may be pareve or dairy, as indicated by the OU designation.
13.3 Margarine
Margarine contains oils and glycerides and requires rabbinic certification. Some margarines are OU Dairy, while others are pareve, depending on the dairy content.
13.4 Non-Dairy Creamers
Many non-dairy creamers are, in fact, dairy and bear an OU-D. The government requires creamers to be labeled “non-dairy” if milk derivatives are used instead of whole milk.

14. Natural and Health Foods
There is a misconception that natural products are inherently kosher. All non-kosher food items are natural, so natural has no bearing on the kosher status.
15. Wines and Grape Products
All grape juice, grape wines, or brandies must be prepared under strict Orthodox Rabbinic supervision. Once kosher wine has been cooked, no restrictions are attached to its handling. Such products are generally labeled “mevushal“. Grape jam, as well as all varieties of jam and jelly, require supervision because they may be processed on non-kosher equipment and may contain non-kosher additives. Grape jelly must be produced from kosher grape juice under proper supervision. Natural and artificial grape flavors may not be used unless they are kosher endorsed. Liqueurs require supervision because of the flavorings and alcohol base used.
16. Traveling
Kosher certified products are widely available in the United States but are harder to find in foreign countries. Travelers can reheat frozen meals in non-kosher ovens by covering the package with two layers of aluminum foil. Microwaves require double wrapping. Kosher meals should be ordered in advance when traveling by plane, train, or ship. Employees are instructed to heat these meals wrapped in double foil with the caterer’s seal and rabbinic certification intact. Any dinner not properly sealed should not be eaten. The kosher certification applies only to the food in the sealed package. Other foods served loose are not included in the kosher endorsement unless they are sealed and bear their endorsement.
