Preheat oven to 350° F.
Grease a 10-inch baking dish. Place in it, in 3 layers:
3 cups pared, very thinly sliced potatoes
Dredge each layer with flour and dot each with butter. Use in all:
2 tablespoons fine, all-purpose flour (we use Wondra)
3 to 6 tablespoons butter
There are many possible additions, in small quantities, to taste:
½ cup finely minced fresh chives or onions (we use very finely minced onions liberally)
¼ cup finely chopped sweet red and/or green sweet peppers (we rarely add these)
1 ¼ cups milk* (we use whole if we have it, otherwise 1 or 2%) dont boil; just look for the little bubbles all around the edge of the pan which are a sign milk has reached scalding temperature
Season warmed milk with
1 ¼ teaspoons salt
¼ teaspoon paprika
¼ teaspoon dry mustard (Colemans if possible)
Pour the milk over the layered potatoes. They should be just barely covered, not swimming in milk, but if the milk is only halfway up the side of the potatoes, add a bit more milk, straight from the frig will do.
Bake potatoes for about 1 ½ hours. They may be covered for the first one-half hour of cooking.
