Scalloped Potatoes
This is the way my mother always made her scalloped potatoes. Some of the measurements are estimated because my mom always just winged it, but the method is the same. The key is to heat the milk first!

Spread about 1/3 of the potato slices into the bottom of the prepared baking dish. Top with about 1/3 of the onion slices. Sprinkle 3 tablespoons flour over the potato and onion. Arrange 2 tablespoons butter atop the flour. Season the entire layer with salt and pepper. Repeat layering twice more.Step 3
