Everyone in our family loves this casserole. It appeals equally to those who are finicky and others with more sophisticated tastes. We like a nonsweet filling, but you can replace the salt with a couple tablespoons of sugar if you prefer. This recipe can be doubled. Then bake it in a larger casserole for about an hour. Depending on the size of your blender, you may need to make the batter for the double recipe in two batches. Serve hot with sour creme.
