Peel a marrow and cut it in half length-ways. Prepare some veal forcemeat by recipe given elsewhere, and make it hot in a saucepan. Remove the seeds from the marrow and put in their place the forcemeat; put the pieces together and bind round with tape. Have ready a fish kettle full of boiling water seasoned with salt; lay the marrow on the drainer and plunge into the water; boil gently for about twenty-five minutes. Slip the marrow carefully into a dish and pour over some melted butter sauce.
Time: 1/2 hour.
