BLACKFISH WITH FINE HERBS
Put the cleaned fish into a baking-dish with chopped onions, parsley and mushrooms. Gash the fish and fill the incisions with butter and chopped onion. Moisten with equal parts of white wine and stock, cover with buttered paper, and cook in a moderate oven for half an hour, basting frequently. Take out the fish, strain the sauce, and add stock to make the necessary quantity. Thicken with a tablespoonful of butter rolled in flour, and pour over the fish. Cover with crumbs, dot with butter, and brown in the oven. Sprinkle with lemon-juice before serving.
