Simmer bananas in butter in an aluminum or agate frying pan covered, on the top of the stove where it is not too hot. They will not be browned but simply stewed.
Cook raisins in a broad flat pan in water for an hour. Slice bananas over, cover and cook 10 m.
Put a thin layer of stewed or sliced tomatoes in the bottom of a baking pan. Cover with bananas sliced crosswise. Bake.
