Wikipedia Abstract
A ham hock is the end of a smoked ham where the foot was attached to the hog's leg. It is the portion of the leg that is neither part of the ham proper nor the foot or ankle, but rather the extreme shank end of the leg bone and the associated skin, fat, tendons, and muscle. This piece generally consists of too much skin and gristle to be palatable on its own, so it is usually cooked with greens and other vegetables in order to give them additional flavour (generally that of pork fat and smoke), although the meat from particularly meaty hocks may be removed and served. Ham hocks or hog jowls (pigs' cheeks) added to various dishes greatly improve their flavour. This is particularly true for cabbage, green beans and navy beans. Ham hocks are essential ingredients in soul food and other forms of American Southern country cooking."
