I just made scalloped potatoes for the first time tonight. I was a little nervous about it, but it was surprisingly easy. slicing the potatoes took a bit, but after that it was a breeze. i topped part of it with grated cheese to test it. it was good with or without it so if you're feeling the cheese then go for it.

3 T all purpose flour
