Buy a potato cutter at a first-class hardware store, and with it cut the potatoes to the size of a hickory nut, and then fry or steam them. When cooked they look just like new potatoes. They are especially nice to garnish meats. You may also parboil and brown in fat, or boil and add parsley as you would with new potatoes. The remainder of the raw potatoes may be boiled and mashed or fried into ribbons.
