kosher [Heb, kasher, fit or proper] , pertaining to the preparation and serving of foods according to Jewish dietary laws (e.g., keeping dairy and meat separate in cooking and ingesting). Kosher foods include common fruits, vegetables, and cereals, as well as tea and coffee. Foods that are not kosher include pork, birds of prey, and seafood that lacks fins and scales, such as lobster and eels. Most poultry and meat products, excluding pork, are kosher if properly processed.
