Why I Love This Recipe
When I was a girl, my mother made wonderful scalloped potatoes for our large family. She made this dish without making a white sauce; she would sprinkle layers of sliced potatoes with flour, salt, pepper, and butter, and pour milk over all, and it would somehow bake into creamy goodness with a crispy and crusty top. Over the years, I tried unsuccessfully to master her method - my attempts would curdle as often as not. I have used this recipe for years, and it consistently turns out well.
