Wipe and cut in pieces three pounds lamb from the fore-quarter. Put in kettle, cover with boiling water, and cook slowly two hours or until tender. After cooking one hour, add one-half cup each carrot and turnip cut in one-half inch cubes, and one onion cut in slices. Fifteen minutes before serving add four cups potatoes cut in one-fourth inch slices, previously parboiled five minutes in boiling water. Thicken with one-fourth cup flour, diluted with enough cold water to form a thin smooth paste. Season with salt and pepper, serve with Dumplings.
