Beutelwurst
A Beutelwurst is a German blood sausage (Rotwurst or Blutwurst), which contains more pieces of fat and flour than a normal Thüringer Rotwurst. The name Beutelwurst comes from the fact that this does not come in a casing of intestine or a can, but in a linen or paper bag ("bag" = Beutel). This bag is pressed for several weeks which gives the Beutelwurst a firm, light, dry consistency. References
