Pigs' knuckles, also known as pork knuckles or ham hocks, are a cut of meat that is unique in flavor and texture. However, sometimes we might need alternative synonyms for this dish. Some useful synonyms for pigs' knuckles are gammon hocks, shanks, trotters, and smoked pork hocks. Gammon hocks refer specifically to the hind legs of a pig that are salted and smoked, making them similar to bacon in flavor. Shanks refer to the leg of a pig, which is often used to make smoked ham. Trotters are the feet of a pig and are often used to make pork jelly. Smoked pork hocks are cured and smoked similarly to ham and have a smoky, savory flavor.
