Marinate split bone-in chicken breasts in white vinegar in a zip lock while the charcoals are heating up. After the coals turn white, place the breasts skin side down on the grill. Close lid on the grill and let slow cook for about half the cooking time depending on the size. Flip the chicken breasts and paint on Patterson's Old Fashioned Mopping Sauce covering completely. Close the lid on the grill and cook almost to finish, flip again and paint sauce on the rest of the meat. Heat until sauce is no longer wet. Remove from the grill and let rest in a covered sauce pan for five or more minutes. Serve whole or cut meat off the bone for salad.
