The main difference between gammon and pork is where it is taken from the pig. Gammon refers to the meat that is taken from the hind legs of the animal.
The term "gammon" came from the French word for hind leg. This cut of meat was taken from the whole pig after it had been smoked or brined.
Today, gammon can be prepared in a variety of ways. Pork cuts like ham come from the rear and front ends of the pig. Pork bacon is cut from the belly, loin, collar or legs of the pig. Pork steaks are taken from the gammon or the back of the pig.
