Fleischbutter (meat butter) is a combination of ground meat, butter, and spices, used as a spread. Fleischbutter is popular in some German regions (south-west), and either unknown or considered inedible in others (north/east). The most common form of fleischbutter is made with ground pork; variants use beef, lamb, kidney, tripe, and other muscle and organ meats. Spices also vary considerably.
A restaurant's breakfast spread might include three or four selections of fleischbutter in small containers, along with containers of butter and jam and chocolate-spread.
