POTATO PUFF

2 cups hot or cold seasoned mashed potatoes
3 tablespoons hot milk
1 egg, separated
2 tablespoons butter or margarine, melted
1 teaspoon grated onion
2 tablespoons cut parsley
1 teaspoon salt
Ground black pepper (to taste)

To the potato add the hot milk, beaten egg yolk, butter or margarine, onion, parsley, salt, and pepper. Mix well.

Beat egg white until stiff and fold into the potato mixture. Pile lightly into a greased baking dish.

Bake at 375 degrees F (moderate oven) for about 35 minutes, or until brown. For a deeper brown, put the dish under the broiler for 3 or 4 minutes.
