Why this works

Salted duck is a dish of restraint: the cure is just coarse salt and wine, two hours minimum, because shorter leaves the meat bland inside and longer than four hours makes it harshly salty. Frying the salt with Sichuan pepper and star anise before it touches the duck is what perfumes the cure — raw spices sprinkled on cold meat never bloom the same way, and the salt must stay below 150 °C or the pepper turns bitter. Wrapping the legs tightly in foil and steaming on low heat, or in a rice cooker's cook mode, cooks them gently without drying, and the centre must reach 75 °C and hold for two minutes. Cooling to room temperature before carving is not optional: hot salted duck shreds and tastes one-dimensional, while cooled duck slices cleanly and its salt and spice settle into balance. Serve sliced on a plain plate, with nothing more than a little of its own juices, so the clean salt flavour stays forward.

Equipment

Steps

  1. Cure the legs. Wash the duck legs and pat completely dry with paper towels. Rub evenly with coarse salt and cooking wine, seal in a bag or wrap in film, and refrigerate for 2 hours. Do not cure longer than 4 hours or the duck will be over-salted.
  2. Fry the salt and spices. In a dry non-stick pan on low heat, fry the coarse salt with the Sichuan pepper and star anise for 3–5 minutes until the salt turns faintly yellow and smells fragrant. Keep the temperature below 150 °C or the pepper will turn bitter.

  4. Bury in hot salt and wrap. Immediately cover the duck legs evenly with the hot fried salt and spices and wrap tightly in foil, sealing well.
  5. Steam gently and cool. Place in a steamer or rice cooker (cook mode) and steam on low heat for 30 minutes, making sure the duck centre reaches 75 °C / 167 °F and holds for 2 minutes. The report suggests a rice cooker's keep-warm setting (80–90 °C) as a gentler alternative to direct heat. Remove, cool naturally to room temperature (about 10 minutes), then chop into pieces and plate, drizzling with a little boiled braising liquid if you have it.

Technique: two hours curing, salt below 150 °C, cool before carving

The two failure points are salt temperature and cure time, and both are unforgiving: salt fried past 150 °C makes the pepper bitter and the whole cure harsh, and a cure past four hours cannot be undone by any later step. Dry the legs thoroughly before curing — water on the surface dilutes the salt and invites uneven seasoning. And do not carve hot: the meat needs its ten minutes of cooling to firm up and let the salt distribute, or it shreds and tastes saltier than it is.

Variations

Frequently asked questions

Why coarse salt, not fine?

Fine salt dissolves too fast and over-salts the surface; coarse salt seasons gradually and is easier to control.

Can I use a rice cooker?

Yes — the report itself suggests it: cook mode for the steaming, or keep-warm (80–90 °C) for a gentler finish.

Why serve it cool?

Cooled salted duck slices cleanly and tastes balanced; hot it shreds and tastes one-dimensionally salty.

Storage and freezing

Best eaten the day it is made, cool. Leftovers keep 2 days refrigerated; serve cool or gently warmed, not reheated hard. Do not freeze the finished dish.
