What each ingredient does
- Duck
- Is the main protein, becoming tender and moist as it cooks slowly in liquid.
- Coarse sea salt
- Seasons the duck during the two-day rest before cooking.
- Butter
- Adds richness and fat to the serving sauce.
- Milk
- Provides the liquid base for the buttery serving sauce in place of water.
The step that matters
Boil the duck slowly. Gentle simmering keeps the meat tender and moist, while a rolling boil can toughen the proteins and make the skin and meat dry.
