Take a little veal forcemeat and season nicely. Sew this into the flathead and truss it into the shape of the letter S. Rub some dripping on to a baking sheet, which should only be just large enough to take the fish. Put some dripping on the top, and bake in a moderate oven for half-an-hour, or longer if large. Slip it on to a hot dish, draw out the trussing string carefully, flavour and boil up the gravy and pour round it. Serve very hot.
Time: 1/2 hour.
