MACKEREL BAKED IN CREAM
Skin and bone a large fish. Cut it into four pieces, season it and fry in butter. Drain it and keep warm. Mix a cupful of white stock with two tablespoonfuls of Sherry and the yolk of an egg. Cook until it thickens, and pour over the fish, seasoning with minced parsley and onion. Sprinkle with crumbs and bake until brown.
