Kosher is a term used to describe food that has been prepared according to Jewish law. The word kosher comes from the Hebrew word kashrut, which means “fit” or “proper.” There are a number of different laws that must be followed in order to prepare food that is considered kosher. These laws govern everything from what types of animals can be eaten, to how the food must be prepared and cooked. Kosher certification is a verification that a food product has been prepared according to these laws.
