A sausage is a food usually made from ground meat, often pork, beef or veal, along with salt, spices and breadcrumbs, with a skin around it. Typically, a sausage is formed in a casing traditionally made from intestine, but sometimes synthetic. Sausages that are sold uncooked are cooked in many ways, including pan-frying, broiling and barbecuing. Some sausages are cooked during processing and the casing may be removed after.Sausage making is a traditional food preservation technique.
