Meanwhile, in small bowl combine orange juice, 3 tsp. of the chili powder, and honey; set aside.
Bake potatoes, uncovered, 25-30 minutes or until tender, brushing three times with orange juice mixture, and shaking pan occasionally.
Meanwhile, in a small bowl combine sour cream, remaining 1/2 tsp. chili powder, and 1/3 cup cilantro. Transfer potatoes to a serving dish; serve with sour cream mixture. Serve immediately or at room temperature.
Tailgate plan:
Place warm potatoes in airtight container. Do not chill. Place sour cream mixture in airtight container and place in insulated container with ice packs.
