Pigs' feet are a common delicacy in many cultures, but sometimes we may want to use a different term to describe this food. Some synonyms for pigs' feet include pig knuckles, trotters, pork hocks, and sow feet. These terms all refer to the same part of the pig, but using a synonym may make the dish sound more exotic or appealing to those who may be less familiar with the traditional preparation. Regardless of what you call them, pigs' feet are a rich source of collagen and protein and are often found in stews, soups, and other hearty dishes.
