Bratwurst is a type of German sausage made from pork or, less commonly, beef or veal. The name is derived from the Old High German Brätwurst, from brät-, finely chopped meat, and Wurst, sausage, although in modern German it is often associated with the verb braten, to pan fry or roast. Beef and veal are usually incorporated amongst a blend often including pork. Beef or veal is usual in halal and kosher Bratwurst sausages, which never include pork for religious reasons.

A sausage is a type of meat product usually made from ground meat—often pork, beef, or poultry—along with salt, spices and other flavourings. Other ingredients, such as grains or breadcrumbs, may be included as fillers or extenders.
