NOTE: This is a very flexible dish. It can bake for an hour at 325'F. or a half-hour at 375'F., so it can go into the oven with something else. You may also substitute evaporated skimmed milk for the heavy cream if butterfat is a concern for you, although the dish will not be quite as pleasing in that case.
