Pig ears

Pig's ear, as food for human consumption, is the cooked ear of pig. It is found in several cuisines around the world. In Bulgaria, a pig's ear is used as an appetizer for beer or wine. It is first boiled and then grilled with lemon, soy sauce, salt, and ground pepper. In Chinese cuisine, pig's ear is often an appetizer or a side dish, called zhū ěr duo , often abbreviated to zhū ěr (豬耳). In some regions, pig's ears are known as ceng ceng cui (层层脆 "layers of crunch"). It can be first boiled or stewed, and then sliced thin, served with soy sauce, or spiced with chili paste. When cooked, the outer texture is gelatinous, akin to tofu, and the center cartilage is crunchy. Pig's ear can be eaten warm or cold.
