[3] Like bacon it must be cooked before it can be eaten; in that sense gammon is comparable to fresh pork meat, and different from dry-cured ham like jamón serrano or prosciutto.
[2][4] The term is mostly used in the United Kingdom and Ireland; other dialects of English largely make no distinction between gammon and ham.
[5] In the United Kingdom and Ireland, joints of cooked gammon are often served at Christmas, but is produced and sold throughout the year.
It can be found in most supermarkets either as a full joint or sliced into steaks, which can then be cooked via pan frying or grilling in a manner similar to bacon.
[6][7] In the 19th century, the word (sometimes extended to the phrase "gammon and spinach") had come to mean "humbug, a ridiculous story, deceitful talk" in Britain.
