Light broiler. Line a baking sheet with aluminum foil; set aside. Rinse wings with cold water and pat dry with paper towels. Place wings on baking sheet skin-side up. Broil wings for 8 to 10 minutes while preparing sauce. NOTE: this step can be omitted, but produces a better tasting wing.
Place wings in the crock of 4 quart slow cooker. In a bowl, stir to combine remaining ingredients. Pour over wings and stir to coat. Place lid on slow cooker and cook on high setting for 2 1/2 to 3 1/2 hours.
