Kochwurst is the name given to the German pre-cooked sausage, a class of sausage whose ingredients are largely cooked before the preparation of the sausage meat. The individual ingredients are held together by solidified fat (as in Streichwürste or string sausages), gelatine (as in Sulz - cured meat in gelatine) or blood proteins coagulated by heating (as in Blutwurst or blood sausage). In contrast with cooked sausages (Brühwurst), Kochwurst does not remain solid on heating, but more or less liquefies. After being filled into intestines, jars or tins, the whole sausage is cooked through again in hot water or steam.
