This is a nice way to utilize left-over Boiled Potatoes. Mash the Potates well, and put them into a frying pan with the butter. Add the yolks of two eggs, well beaten, and stir well, and almost add immediately the cream. Let it get very hot, stirring all the time. Then take the Potatoes from the fire, and add the whites of the eggs, beaten to a stiff froth. Butter a baking dish or biscuit pan, and fill with the mixture. Let it bake in a quick oven till brown. This is an old Creole way of preparing Potatoes, and highly recommended.
