This is one of the most famous and elegant interpretations of Nanjing Saltwater Duck , but elevated with the luxurious addition of fresh or dried osmanthus flowers .
The “ancient method” style emphasizes long marination, gentle low-temperature poaching, and natural cooling in the broth to achieve ultra-tender, juicy meat with crystal-clear skin that glistens like jade and carries a delicate floral fragrance.
The finished duck is served cold or at room temperature and is prized for its silky texture, subtle saltiness, and lingering osmanthus aroma.
- Whole duck — 1 young duck (1.8–2.2 kg / 4–4.8 lb), preferably free-range or high-quality
- Fresh osmanthus flowers — 30–50 g (or 15–25 g high-quality dried osmanthus if fresh is unavailable)
- Coarse sea salt or kosher salt — 120–150 g (for dry brining)
- Sichuan peppercorns — 20 g
- Star anise — 4–5 pieces
- Cinnamon stick — 1 long piece (about 10 cm)
- Bay leaves — 4–5
- Sand ginger (kaempferia galanga, optional but traditional) — 20–30 g fresh or 10 g dried
- Licorice root — 10–15 g (adds subtle sweetness)
- Shaoxing wine — 150–200 ml
- Rock sugar — 40–60 g
- Light soy sauce — 50–80 ml (for color and umami)
- Water — enough to submerge the duck (about 4–5 liters)
- Clean the duck thoroughly:
- Remove any remaining feathers, rinse inside and out.
- Cut off the oil glands at the tail base.
- Pat completely dry with paper towels (very important for crisp skin later).
- Massage coarse salt all over the duck:
- Rub 120–150 g salt evenly inside the cavity, under the skin, and on the exterior.
- Place the duck in a large food-grade plastic bag or container.
- Add 10–15 g Sichuan peppercorns, 2–3 star anise, 1 cinnamon stick, 2–3 bay leaves, sand ginger slices, licorice root, and about 20 g fresh osmanthus flowers (or 10 g dried).
- Pour in 100 ml Shaoxing wine.
- Seal tightly and massage gently so spices distribute.
- Refrigerate 12–24 hours (turn the duck once halfway through).
- Rinse off the salt and spices:
- Remove duck from bag/container.
- Rinse thoroughly under cold Rinse thoroughly under cold running water (inside and out) to wash away most of the salt and loose spices.
- Pat dry again.
- Prepare the poaching liquid:
- In a large pot (big enough to submerge the duck), add 4–5 liters cold water.
- Add remaining star anise, cinnamon, bay leaves, sand ginger, licorice root, rock sugar, light soy sauce, and 50–80 ml Shaoxing wine.
- Add 15–25 g fresh osmanthus flowers (or remaining dried flowers).
- Bring to a gentle boil, then reduce to the lowest simmer (tiny bubbles only).
- Poach the duck (low & slow):
- Carefully lower the duck into the barely simmering liquid (breast side down first).
- Maintain the lowest possible simmer — the water should never reach a rolling boil.
- Poach 25–35 minutes (depending on size):
- 25 min for 1.8–2.0 kg duck
- 30–35 min for larger ducks
- Flip the duck once halfway through.
- Turn off heat. Let the duck cool completely in the broth (4–6 hours or overnight in fridge). This step is crucial — it allows the meat to re-absorb juices and the skin to tighten.
- Final chilling & slicing
- After cooling in broth, transfer duck to a plate.
- Refrigerate 4–8 hours (or overnight) so the skin firms up and becomes glossy.
- Before serving, brush the skin lightly with a little of the chilled, filtered broth for extra shine.
- Serve
- Carve the duck: remove legs and wings first, then slice breast meat thinly.
- Arrange on a plate, skin side up.
- Serve cold or at cool room temperature — no reheating needed.
- Traditionally accompanied by:
- A small dish of the chilled, defatted broth as dipping sauce
- Steamed mantou (steamed buns) or thin pancakes
- Pickled cucumber or radish slices
- Skin translucency → Never boil hard — gentle poaching + cooling in broth = jade-like skin.
- Osmanthus intensity → Fresh flowers give the cleanest, most elegant fragrance. Dried flowers are stronger — use less.
- Salt control → The initial dry brining is heavy — thorough rinsing prevents over-salting.
- Broth reuse → Strain and freeze the poaching liquid — it can be reused 2–3 more times (flavor improves).
- Make ahead → The duck tastes even better the next day. Can be prepared 1–2 days in advance.
- Variations → Some Nanjing masters add a splash of aged soy sauce at the end for deeper color, or a few slices of licorice root in the poaching liquid.
