Haitian bittern juice can be used to pickle duck feet. First cut off the nails of the duck's paw, remove the fascia of the duck neck and wash it for use. Then put the duck's paw and duck neck in water and cook them for later use. Pour rapeseed oil into the pot. When the oil temperature is 60% hot, the rock sugar will turn to a small fire and stir-fry the sugar color. Cook soup stock, cold soup, duck feet, duck neck, Haitian halogen bag, onion knot, ginger slices and high fire. 1 hour later, remove the duck feet and let them cool. Take the salt water out of the pot, cool and soak the duck's paw and duck neck in the salt water for 3 hours.
