Pickled pigs' feet is a type of pork associated with cuisine of the Southern United States, Mexican, Chinese, French Canadian, and Scandinavian cuisine.
The feet of domestic pigs are typically salted and smoked in the same manner as other pork cuts, such as hams and bacon. It is common to preserve them in a manner very similar to home canning and processes for pickled vegetables; typically a saturation of hot vinegar brine is used. Such methods allow them to be preserved without the need for refrigeration until the jar is opened. They were once popular in American bars.[1]
