A few years ago I made a turkey and used the technique of brining. It is very easy and absolutely delicious.
First make a brine (example below):
1 gallon water
1/2 ounce ground cloves
1/2 ounce ground ginger
4 ounces cracked black peppercorns
12 bay leaves
1 pound kosher salt
You can add your favorite spices.
Add all to a stockpot and bring to a boil. Let cool to room temperature. Once cool add rinsed and cleaned turkey making sure the turkey is fully immersed. You may need to add a weight of some sort to the top to keep the turkey down. Marinate for at least 4 hours (I did it over night).
Once finished marinating take turkey out of brine and place in your roasting pan. Cook as directed on package. Enjoy!
