Aluminum foil as turkey roaster rack - Loop and coil up aluminum foil and set under your turkey in order to prop it up.
A good meat thermometer is a must-have, and you should use it during the roasting process, not just to check the bird when you think it's done.
Chicken broth to moisten turkey - It never hurts to have a little extra broth on hand, since you'd rather have too much than not enough. If your turkey turns out a little dry, put the bird into a slow cooker, either whole or cut up, with broth to make it moist again.
