One of the most well-known dietary traditions within Judaism is the prohibition against consuming meat and milk together. This precept is an integral part of the laws of kashrut, the rules that define what is permissible to eat (kosher) according to Jewish tradition. Indeed, kosher cuisine follows well-defined principles originating from the Scriptures, interpreted by rabbis over the centuries.
Why Don’t Jews Eat Meat and Milk Together?
The prohibition of mixing meat and milk is a cornerstone of kosher cuisine and stems directly from the Torah. It is written in three different passages, “Do not cook a kid in its mother’s milk” (Exodus 2319, Exodus 3426, Deuteronomy 14:21). This precept, which might seem limited to the preparation of a specific dish, has been interpreted by rabbis as a broader prohibition against consuming any mammalian meat and milk together.
Rabbinic interpretation has expanded this concept to prevent any type of mixing between meat and dairy, as this combination is considered to lack compassion and respect for animal life. The idea of cooking an animal’s meat in the milk meant to nourish it symbolizes, for Jewish scholars, an act of cruelty. For this reason, kosher rules clearly establish the separation between meat and dairy, not only during meal preparation and consumption but also in the digestion times between the two food types.
According to Jewish tradition, after eating meat, one must wait a period of time before consuming any dairy product. This waiting time varies by community: Sephardic Jews usually wait six hours, while some Ashkenazi Jews wait from three to six hours. The principle behind this wait is to ensure that all the meat has been completely digested before introducing milk or dairy products.
What Are the Rules of Kosher Cuisine?
What Can’t Jews Eat?
Kosher cuisine is based on a complex set of rules that define which foods are permitted and which are prohibited. The animals that can be eaten must meet certain criteria. For instance, only ruminants with cloven hooves are considered kosher. This means that cattle, sheep, and goats are permitted, while pigs, rabbits, and horses are forbidden.
Additionally, even permissible animals must be slaughtered in a specific way, known as shechita. This process, carried out by a kosher butcher called a shochet, ensures that the animal suffers as little as possible and that all blood is completely drained, since the consumption of blood is forbidden by Jewish law.
Regarding fish, only those with fins and scales are considered kosher. This means that fish like salmon, tuna, and trout are allowed, while all seafood, including crustaceans like shrimp, lobsters, and mussels, are prohibited.
Why Don’t Jews Eat Shellfish?
Shellfish are forbidden in the kosher diet because they do not meet the criteria set by the Torah for being considered pure. Jewish law dictates that only fish with fins and scales can be eaten.
Crustaceans such as shrimp, lobsters, crabs, and oysters lack both fins and scales, which is why they are prohibited. This restriction is not just a matter of dietary norms but also a representation of the discipline and attention Jews give to their spirituality through what they eat.
The attention to detail and separation between what is permitted and what is prohibited is part of a conscious way of life that involves every aspect of daily living. Avoiding shellfish, therefore, is not just about health or culinary preferences but represents a commitment to values and traditions handed down through generations.
What Can’t Jews Drink?
Kosher rules also apply to beverages. While most non-alcoholic drinks, such as water and sodas, are generally allowed, there are very precise rules regarding wine.
According to Jewish tradition, wine must be produced and handled only by observant Jews to be considered kosher. This is because wine has a sacred significance in Jewish religious ceremonies, and its production must adhere to specific norms to maintain its ritual purity.
Even some alcoholic beverages like beer and whiskey must be checked to ensure they do not contain non-kosher ingredients, such as animal-derived additives. Some companies produce specifically certified kosher beverages, often marked by special symbols that guarantee compliance with Jewish dietary rules.
Kosher Cuisine in Rome and the Jewish Carbonara
Kosher cuisine is an integral part of Jewish culture and finds a particular expression in Rome, where the Jewish community has influenced the local gastronomy for centuries. In the Jewish Ghetto of Rome, numerous kosher restaurants offer traditional dishes prepared strictly according to the rules of kashrut.
Among the most appreciated specialties is the Jewish carbonara, a variant of the famous Roman carbonara, prepared without forbidden ingredients such as bacon or guanciale. Instead of pork, Jewish carbonara uses permissible alternatives, like turkey or veal meat, thus maintaining the flavor without violating kosher dietary laws.
This dish represents the meeting between Roman culinary tradition and Jewish dietary restrictions, showing how kosher cuisine can be creative and respectful of local traditions.
In the Ghetto’s restaurants, in addition to Jewish carbonara, other specialties like Jewish-style artichokes can be enjoyed, a hallmark dish of Roman Jewish cuisine, symbolizing the fusion between local culture and religious observance.
Jewish Customs at Home and in the Kitchen
Jewish customs at home, particularly in the kitchen, are extremely meticulous, which is also reflected in the management of spaces and utensils. A kosher kitchen is typically organized to prevent any possibility of contamination between meat and dairy. Often, there are indeed two complete sets of pots, pans, dishes, cutlery, and utensils: one dedicated to meat and the other to dairy. Utensil washing is done in separate sinks to ensure that the two categories never mix.
In some homes, especially those that strictly observe kashrut, there are even two ovens and two refrigerators to maintain this separation. The goal is to meticulously follow the rules of the Torah, ensuring that no trace of meat can contaminate milk, and vice versa.
During Pesach (Passover), kosher rules become even stricter. Jews cannot consume yeast, and many prepare specific dishes for this holiday, such as Jewish carbonara, a version of the Roman dish adapted to kosher rules and prepared without pork. Unleavened bread (matzah) replaces leavened bread during this festival.
Besides the separation of meat and dairy, the concept of parve is important in Jewish cuisine. Parve foods are those that contain neither meat nor dairy, such as fish, fruits, vegetables, and eggs. These foods can be consumed with both meat and dairy, making them very useful in the preparation of kosher meals.
