1. Heat your oven or grill to 450 degrees F.
2. Mix all the ingredients into a bowl. *If preparing ahead for a freezer meal, mix the ingredients into a freezer bag and freeze it at this time. Allow thawing completely before continuing with the recipe.
3. For the oven: place chicken in an oven-safe baking dish and pour the sauce over top. For the grill: leave the drumsticks in the marinade until it's time to put them on the grill.
4. Cook until the skin is caramelized and has very dark spots, about 20-30 minutes. On the grill, you'll want to turn your drumsticks every couple of minutes so they cook evenly. Your chicken is done when the internal temperature has reached 165 degrees F.
