The cut of meat from a hog's hind leg, generally from the middle of the shank bone to the aitch (hip) bone. The actual length of the cut varies according to the producer.

Smoking is the process of flavoring, cooking, or preserving food by exposing it to the smoke from burning or smoldering plant materials, most often wood.

In North America, hickory, mesquite, oak, pecan, alder, maple, and fruit-tree woods such as apple, cherry and plum are commonly used for smoking.

In New Zealand, sawdust from the native manuka (tea tree) is commonly used for hot smoking fish. Historically, farms in the western world included a small building termed the smokehouse where meats could be smoked and stored. This was generally well-separated from other buildings both because of the fire danger and because of the smoke emanations.
