Put the chicken, cut up or whole, into a large, heavy-duty gallon Ziploc bag. Mix together the remaining ingredients in a bowl and pour over the chicken, then seal the bag. Make sure that all of the chicken is coated in the marinade. Refrigerate overnight. Grill over indirect heat until the juices run clear when you poke the chicken with a sharp knife.
If you forgot to marinate the chicken overnight, but just can't wait to eat some grilled Jerk Chicken, you can use the Jerk Seasoning as a dry rub. Sprinkle about 1/2 cup of Jerk Seasoning over both sides of the chicken. Now lightly sprinkle salt on both sides of the chicken. Grill...and enjoy!
