The formula is 10 duck, 200g salt, 50g ginger, 100g onion, proper amount of soy sauce, sugar and marinade.
After slaughter and cleaning, put the duck on the dining table, cut a small mouth under the wings with a knife, take out the internal organs, rinse them with clear water, and bend the duck's feet on the back. Add a small amount of water into the pot, cook the duck for a few minutes, then take it out, add the marinade and auxiliary materials to boil (the new marinade can also be prepared with spiced marinade), put it into the pre-cooked duck body, take it out after boiling for 10 minute, drain it, then put it into the pot and cook it for several times until the duck legs become soft, and then take it out and drain it to get the finished product.
