I use 1 or 1/2 pound of ground sausage depending on how much I want to make. Brown the sausage then add enough flour to coat sausage.
Stir then add pepper to taste then add milk or canned milk stirring all the time. How much liquid you use will depend on how thick you want your gravy to be. Cook gravy on a low med. heat so that it will not burn. If it gets too thick just add more liquid. This is the recipe I grew up with.
