Cooking the turkey at a high temperature ... as in Nigella's stuffed butterflied turkey crown. A single turkey breast is available from many shops, which you can roll and stuff yourself.

If you cook it whole it will take about four hours of slow cooking. To speed up the process, butterfly the turkey. This involves removing the backbone, so the bird can sit flat and cook faster.

You can butterfly just about any large piece of boneless roast, whether it’s beef, lamb, turkey or pork ... wooden skewers about an inch apart and cook it to the desired temperature.
