From Wikipedia
Bratwurst is a type of German sausage made from pork or, less commonly, beef, veal, or any combination of beef, veal, and pork. 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.
