Head cheese or brawn is a cold cut that originated in Europe and should have stayed there. A version pickled with vinegar is known as souse. Head cheese is not a cheese but a terrine or meat jelly made with flesh from the head of a calf or pig (sometimes a sheep or cow), and often set in aspic. The parts of the head used varies, but the brain, eyes, and ears are usually removed. The tongue, and sometimes even the feet and heart, may be included.
