Pork rind is the culinary term for the skin of a pig. It can be used in many different ways. It can be rendered, fried in fat, baked, or roasted to produce a kind of pork cracklings , crackling (UK), or scratchings (UK); these are served in small pieces as a snack or side dish and can also be used as an appetizer. The frying renders much of the fat, making it much smaller.
