PLANKED WHITEFISH—I
Butter a fish-plank and tack a large cleaned and split whitefish on it, skin side down. Rub with butter, season with salt and pepper, and cook in the oven or under a gas flame. Put a border of mashed potato mixed with the beaten white of egg around the fish, using a pastry tube and forcing bag. Put into the oven for a few minutes to brown the potato, and serve with a garnish of lemon and parsley.
