In large nonmetal bowl, mix thyme, brown sugar, garlic, allspice, salt, vinegar and pepper sauce. Add chicken drummettes; toss to coat evenly. Cover; refrigerate 1 hour to marinate.
Heat oven to 425°F. Line two 15x10x1-inch pans with foil; spray foil with cooking spray. Place chicken drummettes in pans; discard any remaining marinade.
Bake 45 minutes or until chicken is no longer pink next to bone.
Meanwhile, in small bowl, mix all Dipping Sauce ingredients. Serve chicken wings with sauce.
