Ignames. There are a number of different kinds of yams-and sweet potatoes which grow in the West Indies, the yampois, which comes from Haiti, being one of the best; but the native method of cooking them is always the same—roasting the yams in hot ashes, a practice which is more or less universal whenever sweet potatoes or yams are to be found. In the West Indies the natives select special kinds of wood, and know exactly when the ashes are sufficiently hot—and yet not too hot—to put the potatoes in them, and they are never burnt or undercooked. Sweet potatoes can also be baked in the oven, or boiled. They are served whole in their skins and eaten with butter.
