Cut cold baked sweet potatoes into quarter-inch slices and measure one pint. Melt two tablespoons butter in a baking dish, and when hot lay potatoes in; sprinkle the top with two tablespoons sugar or honey; pour over two tablespoons vinegar and cook until brown and hot. Sweet potatoes are always better twice baked.
