Kosher practices refer to the dietary laws observed in Judaism. These laws dictate what foods are permissible and how they should be prepared. For example, only certain animals, such as cows and sheep, are considered kosher, and they must be slaughtered in a specific way. Additionally, dairy and meat cannot be mixed or consumed together. Another important aspect of kosher practices is the supervision of food preparation. Foods must be certified by a reliable authority, often marked with a hechsher, a symbol indicating that they meet kosher standards. This ensures that all ingredients and processes comply with the laws of kashrut.
