Träipen is a Luxembourg-style black pudding, a blood sausage made by combining ground pork head meat, lungs, kidneys, and tongues or other pork offal with pork blood, cabbage, onions, and stale bread. The sausage mixture is then traditionally seasoned with salt, pepper, and a special variety of summer savory, called bounekräitchen in Luxembourgish, that imparts a unique flavor to this meat specialty.
