n. 1 The rind of pork meat 2 (context US English) a snack food made from cured pork skin, pork scratchings
Wikipedia
Pork rind is the skin (rind) of a pig. Pork rind is a common ingredient of sausages, which helps to improve their consistency. Fried or roasted pork rind and fat is also a snack. The frying renders much of the fat that is attached to the uncooked rind, causing the cooked product to reduce considerably in size. The product may be known by alternative names, such as pork scratchings or pork crackling in the UK, although the term crackling may also refer to the rind atop a roasted pork joint.
