What is a gammon joint?
It is a cured cut from the hind leg. It can be used in Ireland and the U.K. in a boiled dinner of bacon, cabbage and potato. My Mom called it "a joint", "a piece of bacon" or "boiling bacon" although boiling bacon isn't exclusively a gammon joint - confusing, I know. I'm not a butcher but I think this is what is called a ham shank in the U.S.
This article from the Delia website discusses the issue of the incorrect use of "gammon" and "bacon joint" interchangebly. http://www.deliaonline.com/ingredients/ingredients-a-z/ingredients-a-c/Bacon--including-gammon.html

Whatever it is called, it is delicious.
according to thepigsite.com (a website for the global pig industry) it is a ham joint which has been cured like bacon. It is different from a bacon joint in that it is a different cut, although a bacon joint can be used as a lower quality alternative. Gammon can be smoked or unsmoked. I don't think shoulder is typically used.
