The old hen opened (it was pure because the old chicken was too big. So I let the master of the market help open it, the soup only used a part). After the water was soaked and then the water was removed, the blood was removed and the cold water was used.
Sour bamboo shoots, soaked in water, remove excessive sourness and white foam left after pickling, sliced, codonopsis, jujube, medlar and bamboo shoots into cold water pot
Put the prepared chicken pieces into the pot, boil until they boil, then simmer for two hours.
After putting salt, turn to the fire and cook for another 10 minutes.
