1. Understanding Kosher Dietary Laws
The term “kosher,” derived from the Hebrew word meaning “fit” or “proper,” refers to food that adheres to Jewish dietary laws, known as kashrut. These laws, originating from the Torah (Leviticus 11 and Deuteronomy 17), have been interpreted and applied by rabbinic scholars for thousands of years. FOODS.EDU.VN helps you understand these complex rules, offering insights into their practical application and historical context.
1.1. The Core Principles of Kashrut
- Permitted and Forbidden Animals: Kosher meat comes from animals that both chew their cud (ruminants) and have cloven hooves, such as cows, sheep, goats, and deer. Poultry considered kosher includes chicken, turkey, duck, and goose, provided they are slaughtered according to halakha (Jewish law). Fish must have both fins and easily removable scales.
- Separation of Meat and Dairy: One of the most fundamental rules is the separation of meat and dairy. This includes not cooking them together, eating them together, or even preparing them using the same utensils.
- Prohibition of Blood: The Torah strictly forbids the consumption of blood. Meat and poultry must undergo a process called kashering to remove all traces of blood.
- Use of Kosher Utensils: Utensils used for meat and dairy must be kept separate. A kosher kitchen typically has two sets of dishes, cookware, and cutlery.
1.2. The Significance of Rabbinic Supervision
Given the complexity of kosher laws, it’s essential to seek guidance from an Orthodox Rabbi or a reputable kashrut agency. These experts ensure that food products meet the required standards, from sourcing ingredients to processing methods. At FOODS.EDU.VN, we emphasize the importance of reliable kosher certification to maintain the integrity of these dietary practices.
The OU symbol is a widely recognized kosher certification.
2. Detailed Rules for Kosher Meat and Poultry
Understanding what constitutes kosher meat and poultry involves several specific guidelines that ensure adherence to Jewish dietary laws. These regulations cover the types of animals that are permissible, the method of slaughter, and the preparation processes required before consumption.
2.1. Identifying Kosher Animals
The Torah provides specific criteria for determining which animals are kosher. For mammals, the animal must both chew its cud (be a ruminant) and have cloven hooves.
2.1.1. Kosher Mammals
Examples of kosher mammals include:
- Cow
- Sheep
- Goat
- Deer
- Antelope
- Bison
- Giraffe
- Ibex
- Addax
- Gazelle
These animals are permissible for consumption provided they are slaughtered and prepared according to kosher laws.
2.1.2. Non-Kosher Mammals
Animals that do not meet both criteria (chewing cud and having cloven hooves) are considered non-kosher. Examples include pigs, rabbits, horses, and camels.
2.2. Kosher Poultry
Unlike mammals, the Torah does not specify physical characteristics to distinguish between permitted and forbidden birds. Instead, it lists 24 forbidden species. However, due to uncertainty in identifying these species, the practice is to consume only birds with an established tradition of being kosher.
2.2.1. Accepted Kosher Poultry
In the United States, the poultry species generally accepted by mainstream kashrut organizations include:
- Chicken
- Turkey
- Duck
- Goose
2.2.2. Questionable Poultry
Some birds may have questionable status due to lack of clear tradition or identification. These are generally avoided unless certified by a reliable kashrut authority.
2.3. Shechita (Kosher Slaughter)
Shechita is the ritual slaughter of kosher animals, performed by a trained shochet (slaughterer) who is well-versed in Jewish law.
2.3.1. The Process of Shechita
- Training and Piety: The shochet must be a pious individual with extensive knowledge of kosher laws and certified by rabbinic authorities.
- The Blade: A special, razor-sharp, perfectly smooth blade (known as a chalaf) is used.
- The Cut: The shochet swiftly severs the trachea and esophagus of the animal with the chalaf.
- Instantaneous Death: The cut must cause immediate death with minimal pain to the animal.
2.3.2. Purpose of Shechita
- Minimizing Pain: The goal is to ensure the animal dies instantly and without suffering.
- Blood Drainage: Proper shechita facilitates the draining of blood, which is forbidden for consumption.
- Compliance with Torah Law: Adhering to the biblical commandment regarding how animals must be slaughtered.
2.4. Bedika (Inspection)
After shechita, a trained inspector (bodek) examines the internal organs of the animal for any abnormalities that could render it non-kosher (treif).
2.4.1. The Inspection Process
- Lung Examination: The bodek pays particular attention to the lungs, checking for adhesions (sirchot), which may indicate punctures.
- Further Examination: If adhesions are found, the bodek examines them carefully to determine their kosher status.
- Quality Standard: Bedika ensures a high standard of quality that exceeds government requirements, in addition to fulfilling halacha requirements.
2.4.2. Glatt Kosher
“Glatt” literally means “smooth” and refers to meat from an animal whose lungs are completely free of adhesions. While not all adhesions render an animal non-kosher, some communities and individuals prefer to consume only glatt kosher meat.
2.5. Nikkur (Excising)
Nikkur involves the removal of specific blood vessels, nerves, and lobes of fat that are forbidden for consumption.
2.5.1. The Process of Nikkur
- Special Training: Nikkur requires specialized cutting procedures performed by a trained individual.
- Specific Cuts: These procedures are specific to beef, veal, and lamb.
- Removal of Forbidden Parts: Ensures that forbidden parts are properly excised from the animal.
Nikkur is a complex and time-consuming process, which is why specially trained individuals must perform it.
2.6. Kashering Meat: Removing Blood
The Torah strictly prohibits the consumption of blood, so meat must undergo a process to remove all traces of blood. This process is called “kashering.”
2.6.1. Methods of Kashering
There are two primary methods of kashering:
- Salting: Soaking the meat and then covering it with salt to draw out the blood.
- Broiling: Using direct heat to extract the blood, primarily used for liver.
2.6.2. Salting Meat
The process of salting meat involves several steps:
- Soaking: The meat is first soaked in cool water for about half an hour in a utensil designated only for this purpose.
- Salting: After soaking, the meat is thoroughly salted with coarse salt, ensuring the entire surface is covered with a thin layer. Both sides of the meat and poultry must be salted.
- Placement: The salted meat is left for an hour on an inclined or perforated surface to allow the blood to flow freely. The cavity of poultry should be placed open and facing downward.
- Washing: After salting, the meat is thoroughly soaked and washed to remove all the applied salt.
2.6.3. Broiling Meat
Broiling is an alternative method used primarily for liver due to its high blood content:
- Washing: The liver is first thoroughly washed to remove surface blood.
- Salting: Lightly salted on all sides.
- Slitting: Slits are made in the liver to allow blood to escape.
- Broiling: The liver is broiled on a designated liver-broiling perforated grate over an open flame, ensuring the internal blood is drawn out.
- Rinsing: After broiling, the liver is rinsed off.
2.7. Time Sensitivity
Meat must be kashered within 72 hours after slaughter to prevent the blood from congealing. If the meat has been thoroughly soaked before the 72-hour limit, an extension is granted to complete the salting process.
2.8. Ensuring Kosher Standards
From the time of slaughter, kosher meat and poultry must be properly supervised until it reaches the consumer.
2.8.1. Supervision and Packaging
- Metal Tag (Plumba): A metal tag bearing the kosher symbol is often clamped on the meat or fowl as a seal of supervision.
- Tamper-Proof Packaging: Alternatively, the meat or fowl is packed in tamper-proof packaging with the kosher logo prominently displayed.
2.8.2. The Role of the Kosher Butcher
The kosher butcher plays a critical role in distributing the product. They must be a person of integrity, and the store should be under reliable Rabbinic supervision.
3. Kosher Fish: Guidelines and Rules
Identifying and preparing kosher fish involves specific guidelines that ensure adherence to Jewish dietary laws. These regulations cover the types of fish that are permissible, how they should be inspected, and other relevant rules.
3.1. Identifying Kosher Fish
The Torah provides two criteria for determining which fish are kosher:
- Fins: The fish must have fins.
- Scales: The fish must have scales that are easily removable without damaging the skin. Generally, scales on kosher fish are either thin, rounded, and smooth-edged (cycloid) or narrow segments similar to the teeth of a comb (ctenoid).
3.2. Examples of Kosher and Non-Kosher Fish
3.2.1. Kosher Fish
Examples of kosher fish include:
- Salmon
- Tuna
- Cod
- Flounder
- Herring
- Mackerel
- Carp
These fish have both fins and easily removable scales, making them permissible for consumption according to kosher laws.
3.2.2. Non-Kosher Fish
Fish that do not meet both criteria (fins and easily removable scales) are considered non-kosher. Examples include:
- Catfish
- Eel
- Shark
- Sturgeon
All shellfish, including shrimp, crab, lobster, and clams, are also prohibited.
3.3. Inspection and Preparation
Unlike meat and poultry, fish does not require special shechita (slaughter) or kashering (removal of blood). However, there are specific guidelines to ensure the fish remains kosher.
3.3.1. Visibility of Scales
The fish scales must be visible to the consumer to establish the kosher status of the fish. This is important because it confirms that the fish meets the kosher requirements.
3.3.2. Purchasing Fish
Filleted or ground fish should not be purchased unless it is properly supervised or the fillet has a skin tab with scales attached to the flesh. This ensures that the fish is indeed a kosher species.
3.3.3. Avoiding Non-Kosher Fish Stores
Purchasing fish in a non-kosher fish store can be problematic, even if the scales are intact, because the knives and tables may not be kosher. Therefore, it is advisable to seek Rabbinic guidance in such situations.
3.4. Serving and Eating Fish
While fish and meat cannot be eaten together as part of the same dish, they can be consumed one after the other, even at the same meal.
3.4.1. Avoiding Mixing Fish and Meat
To avoid inadvertently eating fish and meat together:
- Separate Dishes and Cutlery: Do not use the same dishes or cutlery without washing them thoroughly between courses.
- Cleansing the Palate: Eat some solid food and drink water or a beverage in between courses to cleanse the mouth of any residue.
3.4.2. Processed and Smoked Fish
Processed and smoked fish products, like all processed foods, require reliable rabbinic supervision to ensure they meet kosher standards.
3.5. Fish Eggs (Roe)
The eggs (or other by-products) of non-kosher fish are not kosher. Caviar, therefore, must come from a kosher fish and requires reliable supervision.
3.6. Cross-Contamination
It is important to ensure that kosher fish is not cooked or prepared on the same equipment as non-kosher foods. Cross-contamination can render the fish non-kosher.
4. The Significance of Separating Meat and Milk
The separation of meat and milk is one of the most fundamental and well-known laws of kashrut. This separation involves not only the food items themselves but also the utensils used to prepare and serve them. Understanding and adhering to these rules is a critical aspect of maintaining a kosher kitchen.
4.1. Biblical Basis
The Torah explicitly forbids:
- Cooking Meat and Milk Together: It is prohibited to cook meat and milk together in any form.
- Eating Such Cooked Products: Consuming any product that contains a mixture of cooked meat and milk is forbidden.
- Deriving Benefit from Them: Gaining any benefit from a mixture of cooked meat and milk is also prohibited.
4.2. Rabbinic Extensions
To safeguard against accidentally violating these commandments, the Rabbis extended the prohibition to include:
- Eating Meat and Dairy at the Same Meal: Meat and dairy products cannot be eaten at the same meal.
- Preparing Them on the Same Utensils: Using the same utensils to prepare both meat and dairy is not allowed.
4.3. Waiting Times Between Meat and Dairy
One must wait a specific period of time after eating meat before consuming dairy products.
4.3.1. Traditions for Waiting Times
Different communities have different traditions for how long to wait. The most prevalent custom is to wait six hours. Other customs range from three to five hours.
4.3.2. Eating Meat After Dairy
Meat may be eaten following dairy products with one exception: hard cheese aged six months or more. This type of cheese requires the same waiting time as dairy after meat.
4.3.3. Actions Before Eating Meat After Dairy
Before eating meat after dairy, one must:
- Eat a Solid Food: Consume a solid food item.
- Drink a Liquid: Drink a liquid such as water or another beverage.
- Rinse One’s Mouth: Thoroughly rinse one’s mouth.
- Check Cleanliness of Hands: Ensure that one’s hands are clean.
4.4. Utensils: Maintaining Separate Sets
A kosher kitchen must have two different sets of utensils: one for meat and poultry and another for dairy foods.
4.4.1. Separate Sets of Utensils
This includes:
- Pots
- Pans
- Plates
- Silverware
These items must be kept separate and distinct to prevent cross-contamination.
4.5. Washing Dishes
Ideally, a kosher kitchen should have two separate kitchen sinks: one for meat and the other for dairy.
4.5.1. Using One Sink for Both
If it is not feasible to have two sinks, dishes and utensils should be placed and washed on a rack so as not to touch the sink. Separate racks are to be used for meat and dairy.
4.5.2. Avoiding Soaking Dishes
Care must be taken to ensure that the water does not rise to the level of the rack. Dishes cannot be soaked in a sink used for both dairy and meat.
4.6. Dishwashers
Using a dishwasher for both meat and dairy is generally not recommended unless the dishwasher is kashered (made kosher) between uses, which is a complex process.
4.7. Surfaces
Countertops and other surfaces used for food preparation should also be kept separate or thoroughly cleaned between meat and dairy preparation.
4.8. Ovens and Stovetops
Ovens and stovetops used for both meat and dairy require careful management to prevent cross-contamination. Using separate oven racks and stovetop burners is advisable.
5. Understanding Pareve Foods in Kosher Dietary Law
In the context of kashrut, the term “pareve” (also spelled parve or parev) refers to foods that are considered neutral—neither meat nor dairy. These foods can be eaten with either meat or dairy dishes, providing flexibility in kosher meal planning.
5.1. Definition of Pareve
“Pareve” means that the food item does not contain any dairy or meat ingredients and has not been processed with heat on dairy or meat equipment.
5.2. Common Pareve Foods
Examples of pareve foods include:
- Fruits
- Vegetables
- Grains
- Legumes
- Eggs
- Fish
- Nuts
- Seeds
- Plant-Based Oils
These foods are naturally neutral and do not pose a conflict with either meat or dairy.
5.3. Potential Issues with Pareve Status
While many foods are inherently pareve, their status can be affected by processing and preparation methods.
5.3.1. Equipment Usage
If a pareve food is processed or cooked on equipment used for meat or dairy, it can lose its pareve status. This is because the equipment can transfer traces of meat or dairy into the food.
5.3.2. Additives and Ingredients
The addition of even small amounts of dairy or meat ingredients can change a pareve food to dairy or meat. For example, a vegetable dish that includes butter (dairy) is no longer pareve.
5.4. Labeling and Certification
Proper labeling and kosher certification are essential for ensuring the pareve status of a product.
5.4.1. OU Designations
The Orthodox Union (OU) provides the following designations:
- OU: Generally indicates that the item is pareve.
- OU-D: Indicates that the item is dairy.
- OU Meat: Indicates that the item is meat.
5.4.2. Checking Ingredients
It is always recommended to check the ingredient list on the label, even for items with an OU symbol, as omissions can occur.
5.5. Specific Food Categories
Certain food categories often have pareve options but require careful attention to ensure their status.
5.5.1. Sherbets
According to government standards, any product labeled “sherbet” or “fruit sherbet” must contain milk and is therefore not pareve. Water ices, however, may be pareve or dairy, which will be indicated by the OU designation.
5.5.2. Margarine
Margarine contains oils and glycerides and requires rabbinic certification. Some margarines may contain up to 12% dairy ingredients, while others are pareve.
5.5.3. Non-Dairy Creamers
Many non-dairy creamers are, in fact, dairy and bear an OU-D. The government requires that creamers be labeled “non-dairy” if milk derivatives are used instead of whole milk.
5.6. Maintaining Pareve Status in the Kitchen
To ensure that pareve foods remain neutral, it is essential to follow certain practices in the kitchen:
5.6.1. Separate Utensils
Use separate utensils for pareve foods that are distinct from those used for meat and dairy.
5.6.2. Clean Equipment
Ensure that equipment used for pareve foods is thoroughly cleaned and free from any traces of meat or dairy.
5.6.3. Cooking Surfaces
Use clean cooking surfaces and avoid cross-contamination with meat or dairy products.
6. The Kosher Status of Eggs: Rules and Guidelines
In kosher dietary law, eggs are generally considered pareve, meaning they are neutral and can be eaten with either meat or dairy. However, there are specific rules and guidelines regarding the kosher status of eggs that one must observe to ensure compliance with kashrut.
6.1. Source of Eggs
The eggs (or other by-products) of non-kosher birds or fish are not kosher. Therefore, only eggs from kosher fowl are permissible.
6.1.1. Examples of Kosher Fowl
Eggs from the following birds are considered kosher:
- Chicken
- Turkey
- Duck
- Goose
6.1.2. Non-Kosher Eggs
Eggs from non-kosher birds, such as ostrich or emu, are not kosher and cannot be consumed.
6.2. Checking for Blood Spots
Eggs of kosher fowl must be checked for blood spots before use. According to Jewish law, if a blood spot is found in the egg, the entire egg must be discarded.
6.2.1. The Inspection Process
- Crack the Egg: Crack the egg into a clear bowl or onto a flat surface.
- Examine the Egg: Carefully examine the egg for any red or brown spots. These spots indicate the presence of blood.
- Discard if Necessary: If a blood spot is found, discard the entire egg.
6.2.2. Determining the Kosher Status of Blood Spots
The laws regarding blood spots can be complex, and opinions vary among different rabbinic authorities. Some authorities differentiate between blood spots found on the yolk versus the white, while others consider any blood spot to render the egg non-kosher.
6.3. Commercial Liquid Eggs
Commercial liquid eggs also require kosher supervision. This is because they may contain additives or be processed on equipment that is not kosher.
6.3.1. Kosher Certification
Look for liquid eggs that have kosher certification from a reliable kashrut agency. This ensures that the eggs meet kosher standards from production to packaging.
6.4. Hard-Boiled Eggs
When hard-boiling eggs, it is important to use a clean pot and ensure that the eggs are cooked in water that has not been used for non-kosher foods.
6.4.1. Peeling Hard-Boiled Eggs
After hard-boiling, peel the eggs and check for any blood spots before consuming.
6.5. Eggs as a Pareve Food
Eggs are generally considered pareve, meaning they can be eaten with either meat or dairy. However, their status can change if they are cooked with meat or dairy ingredients.
6.5.1. Avoiding Cross-Contamination
To maintain the pareve status of eggs, avoid cooking them in utensils or on surfaces that have been used for meat or dairy without proper cleaning.
6.6. Serving Eggs
Serve eggs on clean dishes that have not been used for meat or dairy, or ensure they have been properly washed according to kosher guidelines.
7. The Significance of Kosher Emulsifiers, Flavors, Fillings, and Cremes
In the kosher world, seemingly minor ingredients like emulsifiers, flavors, fillings, and cremes can have a major impact on the kosher status of a food product. These components are often complex and require careful supervision to ensure they meet kosher standards.
7.1. Emulsifiers
Emulsifiers are substances that stabilize mixtures of oil and water, commonly used in a wide range of food products.
7.1.1. Sources of Emulsifiers
Emulsifiers can be derived from either animal or vegetable sources. Animal-derived emulsifiers are not kosher, while vegetable-derived emulsifiers can be kosher if produced under kosher supervision.
7.1.2. Common Emulsifiers
Examples of emulsifiers include:
- Polysorbates
- Glycerides (Mono- and Diglycerides)
- Sorbitan Monostearates
These ingredients are found in products like margarine, cream fillings, toppings, coffee creamers, and baked goods.
7.1.3. Kosher Supervision
Because the source of emulsifiers is not always clear, reliable kosher supervision is essential. Kosher certification ensures that the emulsifiers used are derived from kosher sources and produced on kosher equipment.
7.2. Flavors
Flavors, both artificial and natural, are critical components in nearly every processed food.
7.2.1. Complexity of Flavors
Flavor production is highly complex, using raw materials from various sources. Some ingredients used in flavors may not be kosher.
7.2.2. Kosher-Sensitive Ingredients
Examples of kosher-sensitive ingredients used in flavors include:
- Fusel Oil: May be extracted from grape juice, requiring kosher certification for grape products.
- Glycerin: Can be derived from animal or vegetable sources.
- Castorium: A beaver extract.
7.2.3. Ingredient Declarations
The ingredient declaration typically does not provide a detailed breakdown of the components used in flavors, making kosher supervision necessary to verify their status.
7.3. Fillings and Cremes
Fillings and cremes are used in many baked goods, pastries, and desserts.
7.3.1. Potential Non-Kosher Ingredients
Fillings and cremes may contain:
- Fats: Can be of animal or vegetable origin.
- Emulsifiers: As discussed above, can be derived from non-kosher sources.
- Gelatin Stabilizers: Gelatin is often derived from non-kosher animal sources.
- Flavors: May contain non-kosher components.
7.3.2. Ensuring Kosher Status
All fillings, cremes, and fudge bases must be certified kosher to ensure that all ingredients meet kosher standards.
8. Kosher Rules for Breads, Rolls, Challah, Bagels, and Bialys
These staples present several kosher challenges, necessitating kosher certification. At foods.edu.vn, we guide you through the complexities to ensure your baked goods meet the highest kosher standards.
8.1. Ingredients and Production
Many types of bread are made with oils and shortenings, which can be non-kosher. Basic ingredients of specially prepared dough mixes and dough conditioners are often shortenings and di-glycerides. In bakeries, pans and troughs in which the dough is placed to rise and bake are coated with grease or divider oils, which may be non-kosher. These oils often do not appear on the label. There may also be an issue of other non-kosher products prepared and baked on the same equipment. These are some of the reasons that bread requires kosher supervision.
8.2. Dairy Bread Prohibition
It is Rabbinically prohibited to produce bread utilizing dairy ingredients. Since bread is frequently eaten at all meals, the Rabbis were concerned that one might inadvertently eat dairy bread with a meat meal. There are two exceptions – if the bread is baked in an unusual shape or design indicating that it is dairy, or if the loaf is so small that it would be consumed at one meal.
8.3. Challah – Separating a Portion
Jewish law requires that a portion of batter or finished baked product be set aside for what is known as “challah.” While any size portion is adequate for challah, it is customary to separate a portion the size of an olive. After separation, the challah is burned. This ritual is obligatory only when the owner of the dough at the time of its preparation is Jewish, and the dough is made from flour of any of the following five grains: wheat, oats, rye, spelt, and barley. In addition, 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.
8.4. Performing Mitzvah at Home
If this mitzvah has not been performed in the bakery, it may be performed in the home by placing all the baked goods in one room, breaking open all sealed packaged material, and taking a small piece from any of the baked goods and burning it.
:max_bytes(150000):strip_icc():format(webp)/21353ChallahBreadIIMarkStewart-1×1-1-b83e2b09266e43199238734a65c2086b.jpg)
Challah is a traditional Jewish bread.
9. Kosher Observance in Catering, Restaurants, and Hotels
Maintaining kashrut in catering, restaurants, and hotels requires strict adherence to kosher laws and reliable supervision.
9.1. The Importance of Reliable Supervision
Caterers, restaurants, and hotels must be supervised by a reputable Orthodox Rabbinic authority to ensure that all food preparation and serving processes comply with kosher standards.
9.2. Common Misconceptions
It cannot be assumed that kashrut is maintained simply because a kosher impression is created by an advertisement or by a statement, such as, “we serve a kosher clientele.” Too often, ‘vegetarian’ or ‘dairy’ restaurants are assumed to be kosher and beyond the need for supervision.
9.3. Hidden Kosher Issues
Unfortunately, this is a prevalent misconception. Fish, baked goods, cheese, shortening, oil, eggs, margarine, dressings, and condiments are among the many foodstuffs requiring supervision in ‘vegetarian’ and ‘dairy’ restaurants. Even those food items that are kosher in their raw states could be rendered non-kosher when prepared on equipment used for non-kosher food.
9.4. Equipment
Using equipment, such as ovens or grills, for both kosher and non-kosher food items can render even inherently kosher foods non-kosher.
9.5. Specific Supervision Needs
Even those food items that are kosher in their raw states could be rendered non-kosher when prepared on equipment used for non-kosher food. For these reasons, reputable kosher supervision is required.
10. Kosher Wine and Grape Products: Regulations and Guidelines
The production and consumption of wine and grape products have specific regulations within kosher dietary law.
10.1. Supervision Requirements
All grape juice, grape wines, or brandies must be prepared under strict Orthodox Rabbinic supervision. This is because of the unique laws pertaining to wine that are stricter than those for other foods.
10.2. Handling by Non-Jews
According to Jewish law, wine handled by non-Jews may not be kosher unless it has been cooked.
10.3. Mevushal Wine
Once the kosher wine has been cooked, no restrictions are attached to its handling. Such products are generally labeled “mevushal.”
10.4. Grape Jam and Jelly
Grape jam (produced from grape pulp) 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.
10.5. Grape Jelly
Grape jelly is produced from grape juice and can be used only when produced from kosher grape juice under proper supervision.
10.6. Grape Flavors
Natural and artificial grape flavors may not be used unless they are kosher endorsed. Many grape flavors contain natural grape extracts and are labeled artificial or imitation because other flavoring additives are used in the formula.
10.7. Liqueurs
Liqueurs require supervision because of the flavorings used in these products. In addition, the alcohol base may be wine-derived.
11. Natural and Health Foods: The Kosher Perspective
With the proliferation of so-called “Natural” or “Pure” and similarly promoted health food products in the United States, some clarification is in order with regards to their kashrut status.
11.1. The Misconception
There is a mistaken notion that natural products are inherently kosher. In fact, all non-kosher food items are natural, and therefore natural has no bearing on the kosher status.
11.2. Supervision Still Needed
Just like any other food product, natural and health foods require reliable kosher supervision to ensure they meet kosher standards.
12. Kosher Dietary Guidelines for Travelers
Maintaining a kosher diet while traveling can be challenging but is entirely possible with proper planning and knowledge of available resources.
12.1. Availability of Kosher Products
For the businessperson or tourist traveling across the United States, kosher-certified products are available almost everywhere, even in the smallest groceries in the most remote towns.
12.2. International Travel
However, it is much more difficult to obtain reliably kosher-certified products in most foreign countries.
12.3. Bringing Frozen Meals
A traveler bringing along frozen (TV) dinners where only non-kosher ovens are available for reheating may use the ovens by covering the frozen package with two layers of aluminum foil. If a microwave will be utilized, then the food must also be double-wrapped.
12.4. Ordering Kosher Meals
Kosher meals should be ordered in advance when traveling by plane, train, or ship. These meals are also heated in non-kosher ovens. The employees of the carrier are instructed to heat these meals in the same manner that they were received; totally wrapped in double foil with the caterer’s seal and the Rabbinic certification seal intact.
12.5. Verifying Seals
The traveler can ascertain by the intact seals that the dinners have not been tampered. Any dinner that is not properly sealed should not be eaten. The kosher certification only applies to the food in the sealed package.
12.6. Additional Items
Any other food (rolls, wines or liqueurs, cheeses, and coffee creamers or snacks) served loose by the carrier is not included in the kosher endorsement unless it is sealed and bears its own separate endorsement.
13. FAQ: Addressing Common Questions About Kosher Food
