Jiaozi is a common food in northern winter. Mind you, the stuffing is carefully stored in the jiaozi. Cooked fillings can be refrigerated in jiaozi, while uncooked fillings must be frozen to ensure the quality. Dumpling stuffing storage is very particular! Chopped stuffing comes into contact with more bacteria, so raw dumpling stuffing must not be stored at room temperature, otherwise it may deteriorate.
It's best to put the uncooked dumpling stuffing in the refrigerator. Otherwise, it should be cooked, disinfected and stored in cold storage. In order to prevent the cooked stuffing jiaozi from producing nitrite during storage, the frozen stuffing jiaozi should be eaten as soon as possible. When eating, it must be sterilized at high temperature by steaming or frying.
