Head cheese or brawn is a cold cut that originated in Europe. A version pickled with vinegar is known as souse. Head cheese is not a dairy cheese, but a terrine or meat jelly made with flesh from the head of a calf or pig, or less commonly a sheep or cow, and often set in aspic. The parts of the head used vary, but the brain, eyes, and ears are usually removed. The tongue, and sometimes even the feet and heart, may be included.Head cheese may be flavored with onion, black pepper, allspice, bay leaf, salt, and vinegar. It is usually eaten cold or at room temperature as a luncheon meat. It can also be made from quality trimmings from pork and veal, adding gelatin to the stock as a binder.
