Start a wood fire. Keep feeding the fire for about half an hour until a good bed of coals is built up. Allow the fire to die down to coals. Bury the potato in the coals and leve it there for about an hour. Feed the fire lightly to maintain coals but not much flame. Dig the potato out of the coals. The skin will be carbonized, but the insided will be yummy.
