What each ingredient does
- Duck
- The main meat, cooked whole by gentle boiling in its wrapping.
- Coarse sea salt
- Draws moisture out of the meat and seasons it deeply during the long salting.
- Onions
- Provide the sweet, savory base of the sauce as they soften.
- Milk
- Gives the onion sauce a creamy, smooth body.
The step that matters
Salting the duck for about 30 hours. Salt slowly penetrates the meat, seasoning it and drawing out surface moisture, so the timing matters. Too short leaves the meat bland, and too long can make it overly salty and dry.
