Clean a four-pound bluefish, sprinkle with salt and pepper, and put on buttered fish-sheet in a dripping-pan. Add three tablespoons white wine, three tablespoons mushroom liquor, one-half onion finely chopped, eight mushrooms finely chopped, and enough water to allow sufficient liquor in pan for basting. Bake forty-five minutes in hot oven, basting five times. Serve with Sauce à l’Italienne.
