Mix milk, yolks, butter, salt and pepper, and add the whites last. Pour into a hot pan, which has been well buttered, and cook quickly on top of oven. When it begins to thicken, put inside the oven and brown. Fold in half and roll and serve hot. Omelets should be served immediately.
Variation: Add 1/2 cup chopped ham, bell peppers, onions to the skillet and saut over high heat in 1/2 tbsp. additional butter, until cooked. Gather these ingredients into the center of the pan with your spatula and spread evenly. Proceed as above, pouring the egg batter over the additions.
