1Heat the bacon drippings in a large heavy skillet. Combine the flour, salt, and pepper, and sift the mixture over the drippings. Blend well, stirring often to keep the mixture from sticking or burning, cook over medium heat. Add the tomatoes to the roux and stir well. If too thick, add a little boiling water. If too thin, add a little more thin flour paste, about the consisitency of buttermilk. Reduce the heat to low and keep warm for second helpings. If you like, add 1 tablespoon of sugar.
