It's all gravy!

"Gravy, American style, is composed of three elements: fat, flour and liquid. The fat can come from the cooking pan, or an outside source such as butter or bacon fat. The liquid can be composed of stock, pan juices, wine, milk, coffee, water — American ingenuity has produced countless variations, like red-eye gravy and sawmill gravy, made from the crusty bits of breakfast sausage in the frying pan." Gotta love American ingenuity!
