Liverwurst, leberwurst, or liver sausage is a kind of sausage made from liver. It is eaten throughout Europe, as well as North and South America, notably in Argentina and Chile.
Some liverwurst varieties are spreadable. Liverwurst usually contains pigs' or calves' liver. Other ingredients are meat (notably veal), fat, and spices including ground black pepper, marjoram, allspice, thyme, ground mustard seed, and nutmeg. Many regions in Germany have distinct recipes for liverwurst. Adding ingredients like pieces of onion or bacon to the recipe make each variety of liverwurst very important to cultural identity. For example, the Thüringer Leberwurst (Thuringian liverwurst) has a Protected Geographical Status throughout the EU. Recently, more exotic additions such as cowberries and mushrooms have gained popularity.
