Put the cold water in the marinade bag together with the things to be marinated. After the tsaoko is marinated, remove the marinade bag and throw it away. Remember to taste the salty salt. The marinated bag must be picked up, and the first cooking time should not be too long, because according to the principle of traditional Chinese medicine, the medicinal properties of traditional Chinese medicine will change if it is cooked for too long, and the color of the things you marinate will turn black. It is best to pick up the cooked medicine bag and put it in the refrigerator for next use.
