BAKED CODFISH WITH CHEESE SAUCE

Rub the fish with butter and lemon-juice, put it on the grating in the baking-pan, season with salt and pepper, and bake, pouring a cupful of white stock under the grating. Take up the fish, cover with crumbs, dot with butter, and brown in the oven. Strain the liquid, thicken with butter rolled in flour, and season with lemon-juice, grated onion, and four tablespoonfuls of grated Parmesan cheese. Bring to the boil and serve poured around the fish.
