mutton

While most foods in Ireland are likely to excite only moderate levels of controversy, people can get really excitable over Irish stew.

(It should be mentioned here that in Ireland it's not usually referred to as "Irish stew", but as "lamb stew".)

It seems possible to get into an argument about nearly anything about lamb stew (except the potatoes). Some folks will complain that you shouldn't really be using lamb to make it at all, but mutton (in other words, the meat from mature sheep, one to three years old, rather than from sheep less than a year old). Fortunately, after a downswing in its popularity, in many places it's becoming possible to find good mutton again if you're willing to look a little.

Other people will get all steamed up about the actual cut of lamb you should be using. Many people insist it should be one of the cheap cuts that requires long, slow cooking, like shin or "scrag end". Others say you should use better cuts, lamb chops from the neck or shoulder, or just plain old chopped up "stewing lamb" bought from the butcher, normally offcuts from the leg or round. You also get people who insist that, whatever the cut of meat involved, the real business of the stew is in the spicing, and that all modern or "fancy" spices should be excluded -- meaning that (in this school of thought) the only spicery proper for a lamb stew is salt, pepper and parsley.

But the liveliest arguments tend to start up over the issue of the presence or absence of carrots...
