FILLETS OF STRIPED BASS À LA BORDELAISE

Clean two striped bass and cut into fillets. Cover the trimmings with water, add one cupful of white wine, two cupfuls of white stock, a sliced onion, a bay-leaf, a sprig of thyme, a tablespoonful of butter, and salt and pepper to season. Skin the fillets, season with salt, and marinate for half an hour in oil and lemon-juice. Drain, sprinkle with flour, dip in egg yolks beaten smooth with a little melted butter, then in crumbs. Broil carefully, basting with melted butter as required. Fry a tablespoonful of chopped onion in two tablespoonfuls of flour and cook to a smooth paste. Add the liquid strained from the fish trimmings and cook until thick, stirring constantly. Add half a cupful of stewed and strained tomato, a tablespoonful of minced parsley, and two tablespoonfuls of butter. Season with red pepper and lemon-juice, pour over the fish, and serve.
