Head cheese is a food made from the head of a pig or cow. Don't worry, it's not actually made from cheese! The head is boiled until the meat falls off the bones, and then the meat is mixed with spices and other ingredients. The mixture is then poured into a mold and left to cool, so it becomes a solid mass. When it's cold and solid, the mold is removed and the head cheese is sliced into pieces. Some people like to eat it cold or add it to sandwiches. It might look a bit strange, but it can be tasty!
