01 - Set oven temperature to 375°F and ensure rack is positioned in the center.
02 - Combine five-spice powder, kosher salt, black pepper, soy sauce, honey, rice wine, minced garlic, grated ginger, and chopped green onions in a small bowl, mixing thoroughly to form a consistent paste.
03 - Rub the prepared marinade thoroughly over the entire duck surface, both inside and out, using your hands to massage the mixture into the skin and meat.
04 - Place the orange quarters inside the duck cavity to infuse citrus flavor during cooking.
05 - Secure the legs together with kitchen twine and tuck the wing tips underneath the body to ensure even cooking.
06 - Position the duck breast-side up on a roasting rack set inside a roasting pan, then pour 1 cup of water into the bottom of the pan beneath the rack.
07 - Roast the duck for 1 hour, basting every 30 minutes with the accumulated pan juices to promote browning and moisture retention.
08 - Increase oven temperature to 425°F and continue roasting for an additional 20 to 30 minutes to achieve crispy, golden-brown skin, monitoring closely to prevent burning.
09 - Remove the duck from the oven and allow it to rest for 15 minutes before carving, enabling juices to redistribute throughout the meat. Discard the orange quarters from the cavity.
10 - Carve the duck into serving portions and accompany with steamed rice, stir-fried greens, or traditional pancakes with hoisin sauce.
