The cooking time of jiaozi needs to be adjusted according to the size and quantity of jiaozi. Generally speaking, quick-frozen dumplings need to be boiled for about 10 to 15 minutes, but the specific time needs to be adjusted according to the actual situation.
If jiaozi is large, the cooking time will increase accordingly. At the same time, if the quantity of boiled jiaozi is relatively large, it is necessary to appropriately extend the cooking time to ensure that all jiaozi can be cooked well.
