Key Lime Barbecue Chicken Wings

1 cup ketchup
1/4 cup fresh lime juice
2 Tbsp liquid smoke (optional)
1 Tbsp Worcestershire sauce
1 Tbsp balsamic vinegar
2 Tbsp brown sugar, packed
1 tsp hot pepper sauce, or to taste
1 tsp granulated garlic powder
1/4 cup minced sweet onion
4 pounds meaty chicken wing pieces, joints separated 
  and tips discarded, about 24 pieces

Marinade:
In a small bowl, combine ketchup, key lime juice, 
liquid smoke, Worcestershire sauce, balsamic vinegar, 
brown sugar, hot pepper sauce, garlic powder, 
and sweet onion. Stir until well-combined. 
(Yields about 1-1/2 cups of marinade.) 

Place chicken wing pieces into a large freezer zip-top 
bag. Pour in the marinade, squeeze out the air, and seal. 
Turn bag over and over until chicken wings are coated 
with the marinade. Refrigerate at least two hours or 
overnight. 

Preheat oven to 325 F. Place wings on a baking rack nestled 
inside a baking pan. Bake about 1-1/2 hours, basting with 
BOILED marinade sauce during the last half hour. 

Yield: 8 appetizer or 3 entree servings
