Saute the bacon in a fry pan over medium high heat until brown. If pan begins to smoke the heat is too high.
peel and slice potatoes about 1/4 thick and arrange a layer of the potatoes in a greased baking dish.
**(note: the recipe does not specify what to grease the dish with, although usually it was a type of lard. for this recipe I use butter.)
sprinkle a layer of the bacon, dust with flour, salt and pepper and repeat layers. Pour milk over layered potato casserole and cover with foil.
Bake for about one hour, or until potatoes are tender. uncover for the last 10-15 minutes of cooking time to allow top to brown slightly.
