5 medium potatoes
5 small onions
2 tablespoons butter
1 tablespoon flour ( **or cornstarch )
1/4 cup heavy cream
3/4 cup water
1 teaspoon salt

Combine heavy cream and water and add to butter/flour mixture. Cook till mixture thickens, stirring constantly. Add salt and pepper. Pour over potatoes and onions in casserole dish. Bake in 350F oven till done, about 60 - 70minutes.

** If you are using cornstarch the sauce is prepared a little differently. Melt butter or margarine in saucepan. Place the cornstarch in small bowl, add the cream / cold water mixture to the cornstarch and stir well to blend. Now add to melted butter or margarine in saucepan and cook till sauce thickens. Add salt and pepper. Pour over potatoes and onions in casserole dish. Bake.
