BAKED FLOUNDER À LA BONVALLET
Put a cleaned flounder into a baking-pan with salt, pepper, grated nutmeg, chopped onion, a tablespoonful of butter, a wineglassful of white wine, and a cupful of white stock. Bake carefully, basting as required. Take up the fish, add another cupful of stock, and thicken the sauce with two tablespoonfuls of flour, blended with an equal quantity of butter. Take from the fire, add the yolks of three eggs well beaten and a tablespoonful of minced parsley. Spread this sauce over the fish, cover with crumbs, dot with butter, and brown in the oven. Sprinkle with lemon-juice and serve.
