01 - Preheat oven to 375°F.
02 - Combine five-spice powder, salt, pepper, soy sauce, honey, rice wine, garlic, ginger, and green onions in a small bowl, mixing thoroughly to form a paste.
03 - Rub the marinade paste all over the duck, covering both exterior and interior cavities. Massage the seasoning into the meat thoroughly.
04 - Stuff the duck cavity with orange quarters. Tie legs together with kitchen twine and tuck wings securely under the body.
05 - Position duck breast-side up on a rack set inside a roasting pan. Pour 1 cup of water into the pan bottom beneath the rack.
06 - Roast for 1 hour, basting every 30 minutes with accumulated pan juices to maintain moisture.
07 - Increase oven temperature to 425°F for the final 20 to 30 minutes to render fat and crisp the skin. Monitor closely to prevent burning.
08 - Remove from oven and let duck rest for 15 minutes to allow juices to redistribute. Remove and discard orange quarters before carving.
09 - Carve and serve with steamed rice, stir-fried greens, or pancakes with hoisin sauce.
