Brush half of the reserved marinade onto chicken and turn the wings over. Bake for another 15 minutes.
Turn chicken a final time and brush on the remaining half of the reserved marinade. Bake until tender and caramelized, another 15 minutes. Let cool for 5 minutes before serving.
Notes
Habaneros are very hot peppers, use gloves when removing the seeds.
