Place two cups of milk into a pan and heat just until a skin forms on top. Set aside. Beat the first four ingredients together then add the scalded milk, tempering the eggs first. To temper eggs, add a little of the egg mixture slowly to the hot milk, stirring constantly. Then slowly add the milk back to the remainder of the egg mixture. Pour into a casserole dish or pie pan. Sprinkle nutmeg on top to taste. Set pan into another larger dish with water in it (a cookie sheet with a lip is fine). Bake at 325 degrees. Center should still be a little soft when done. It will set as it cools.
