First of all, we should prepare the ingredients needed to cook duck stew with Ulmus pumila: Ulmus pumila, duck, onion, ginger, cooking wine, Lycium barbarum, edible salt, clear water and fragrant leaves.
Clean the onion and make it into a ball. Clean the ginger and cut it into pieces. After the Ulmus pumila is cleaned, the roots are cut off. Duck is a clean fresh duck in the market. Rub half a spoonful of salt into the belly of the duck. This can make the duck more tasty, chop the duck into pieces, and keep the duck legs intact.
Clean the pot and pour in the right amount of water. Open a big fire to boil the clear water, and pour the chopped duck into the boiling water. After boiling for four minutes, scoop up the duck. Put the chopped duck in a casserole, and put the elm mushroom, fragrant leaves, ginger slices, onions and wolfberry fruit on top of the duck. Add clear water, and the amount of clear water is subject to the ingredients. Cover the casserole and stew for three hours. Sprinkle a proper amount of edible salt when cooking.
