Lightly butter four 6-ounce custard cups. Place on a baking sheet. Line each with piece of ham, pleating to fit.
Break 1 egg into each cup. Sprinkle with salt and pepper. Pour half-and-half over each; cover with foil.
Bake the egg cups in a 350 degree F oven 20 to 25 minutes or until eggs are firm and whites are opaque. If you like, garnish with some cheese or herbs. Makes 4 servings.
