Żymlok is a traditional Silesian blood sausage consisting of a mixture of pork blood, bread rolls, ground pork offal, onions, spices, and seasonings stuffed into intestines. The ground meat is cooked in meat broth and the bread rolls are soaked in the same broth before they are combined and added to the intestines.
Bread rolls are called żymła in Silesian and bułka in Polish, hence the name of this sausage. Żymlok is usually flavored with aromatic spices such as marjoram, nutmeg, black pepper, bay leaves, allspice, and juniper berries. Although it appears to be a regular sausage, its consistency is similar to black pudding.
