BOURBON-MOLASSES CHICKEN DRUMSTICKS

4 SERVINGS

1/4 cup (1/2 stick) butter
1 cup minced onion
1 cup ketchup
1/4 cup molasses
2 tablespoons (packed) brown sugar
1-1/2 tablespoons Worcestershire sauce 
2 teaspoons yellow mustard 
3/4 teaspoon ground black pepper, divided
1/4 teaspoon chili powder
1/4 cup bourbon

1-1/2 teaspoons coarse kosher salt 
12 chicken drumsticks

Melt butter in large saucepan over medium heat. Add onion; saute until soft, about 6 minutes. Add next 5 ingredients, 1/4 teaspoon pepper, and chili powder. Reduce heat to medium-low; simmer until sauce thickens, about 15 minutes. Stir in bourbon; cook until heated through, about 3 minutes. Season with salt. (Can be made 1 day ahead. Cover and chill.)

Mix 1-1/2 teaspoons salt and 1/2 teaspoon pepper in bowl. Loosen skin on drumsticks. Rub salt and pepper mixture under skin without tearing skin. Cover; let stand at room temperature 30 minutes.

Prepare barbecue (medium heat). Grill drumsticks until skin is crisp and juices run clear, turning to cook all sides, about 25 minutes. Transfer 1/2 cup barbecue sauce to small bowl; reserve. Brush drumsticks with remaining sauce and cook until glaze forms, about 3 minutes longer. Transfer drumsticks to platter and serve with reserved sauce.
