1. Preheat oven to 450 degrees F.
2. Cut each scrubbed and unpeeled potato into 1-inch-thick wedges. Place in a container with a tight-fitting lid and toss with olive oil, salt, and pepper.
3. Cover two metal pans with aluminum foil for easy clean up, if desired and arrange the wedges on the two pans.
4. In a small bowl, combine orange juice, 3 tsp chili powder, and honey.
5. Bake potatoes, uncovered, 25 to 30 minutes, or until tender, brushing three times with orange juice mixture, and shaking pan occasionally.
6. Meanwhile, in a small bowl combine sour cream, 1/2 teaspoons chili powder, and 1/3 cup cilantro.
7. When potatoes are tender, transfer to a serving dish, and serve with sour cream mixture. Serve immediately or at room temperature.
