Recipe for a foolproof turkey (even I can do it): Buy a box of those Reynold Cookin Bags. The instructions are on the box and also on a paper inside. They cost a little but it totally takes the anxiety out of cooking a turkey, ham, roast, anything you want to do in the oven. The cooking times vary when using the bags so be sure to use their instructions. Also, you will need a couple tablespoons of flour, a few slices of onion and come celery stalks. Salt and Pepper. I also sprinkle poultry seasoning on my turkey but it's not necessary. I find the cost is worth taking the worry out of it. Be sure you buy the right size (it says the size clearly on the box). Believe me, it will be the best turkey you ever ate.

PS: Make sure your turkey is thawed completely and those silly things they stick in each end are out. For a frozen turkey, thawed minimum of three days in refrigerator. Or, two and half days in sink full of cold water. Never, ever put a partially frozen turkey in the oven.
