Place the chicken in a large pot. Combine the rest of the ingredients (soy sauce, vinegar, oil, SweetLeaf®, bay leaves, garlic, and peppercorns) in a bowl and whisk. Cover the chicken with the marinade in a bowl or plastic baggies and refrigerate for a few hours or overnight.
Preheat the oven to 400 degrees F. Remove the chicken from the marinade, place in a large baking dish, and bake in the oven for 35 to 40 minutes or until cooked through.
While the chicken is baking, reduce the marinade by heating it in a pot over the stove on medium high heat. Bring it to a boil and allow the liquid to reduce by half. Spoon or brush the reduced liquid over the chicken while baking in the oven, allowing the skin to crisp up with the sauce.
