Kosher refers to a set of dietary laws observed in Judaism that dictate what foods are permissible for consumption. These laws are derived from the Torah, the central reference of the religious Judaic tradition. Foods that are considered kosher must meet specific criteria, such as the type of animal, how it is slaughtered, and the separation of meat and dairy products. In addition to the types of food, kosher laws also govern food preparation and handling. For example, utensils and cooking surfaces must be designated for either meat or dairy to avoid cross-contamination. Observing these laws is an important aspect of religious practice for many Jewish people.
