Dress and cut three flounders into a dozen fillets; dip the fillets in melted butter, sprinkle with salt, pepper, and lemon juice; or let stand in a marinade an hour or more. Fold each fillet around a bit of raw pared potato (this will keep the fillet in the desired shape) and arrange in a baking dish; half cover with hot fish stock, made of the trimmings, and cook in the oven about ten minutes.
