Irish Stew is a popular dish; it is usually made by placing in a stew-pan alternate layers of pieces of mutton and sliced potatoes and onions, with pepper and salt, barely covering them with water, and allowing the whole to stew for some hours. If a large quantity of potatoes are required, it is desirable to partially boil some small ones and place them on the top of the stew half an hour or more before serving, as they then become perfectly cooked and acquire the flavour of the stew. If too many potatoes are added at first, so much water is required to cover them that the stew is spoiled.
