Corned beef and cabbage , as we now know it, has its roots in Atlantic Canada..not in America. It is still a very common dish in Newfoundland and in Nova Scotia.In America I believe it is often called Jiggs dinner, after the cartoon character, but it is an east coast Canadian tradition , brought by the Irish who ate it as salt beef and cabbage. My Father , who came from Cork, was certainly very familiar with the dish.
