Notes: If you use a mix for the cornbread, you'll need 1 box (13 oz.). The dressing can be made up to 1 day ahead; cover and chill. If stuffing turkey, just before roasting, fill neck and body cavities with dressing. Extra dressing can be heated, covered, in a microwave oven on full power (100%) for 5-minute intervals until steaming. Roast turkey as directed. If desired, add fresh or dried herbs such as thyme to roasting juices and baste bird with them as it cooks.
