Chicken wings basted with an orange-soy-ginger sauce are served with a mango-orange dipping sauce.
In small saucepan, combine all the sauce ingredients. Boil sauce over medium-high heat for 10 minutes. Cool sauce to room temperature. If desired, remove garlic and ginger, transfer sauce to tightly covered container, and refrigerate for up to 24 hours.

Brush wings on both sides with sauce and bake, smooth side up, for 5 minutes. Brush with sauce again and bake, underside up, for 5 minutes. Brush wings a third time and bake, smooth side up, for 5 minutes. Brush wings again, and bake, underside up, for 10 minutes. Reduce oven to 400 degrees F. Brush tops of wings with sauce and bake, topside up, for 10 minutes.
