SPANISH MACKEREL À L'ESPAGNOLE

Put a cleaned Spanish mackerel in a buttered pan with one cupful each of wine and white stock. Season with salt, pepper, and grated nutmeg, add a bunch of parsley, and a clove of garlic, cover with buttered paper, and simmer for forty minutes. Take up the fish, thicken the sauce with browned flour, season with lemon-juice and melted butter, pour over the fish, and serve.
