Cut bacon up into 1/2 inch squares. Fry completely. in a seperate bowl, dissolve the flour in milk. keep all the drippings in the pan, and add the milk mixture, much like you would if you were making gravy. Keep stiring, adding salt and pepper to taste. Once mixture thickens, place pan in the middle of the family table, and start dipping your bread, much like a fondue. quick, easy, and delicious!
