Frozen jiaozi does not need to be thawed and can be steamed directly. Steaming frozen jiaozi requires steaming in a pot with cold water, so that the frozen dumpling skin will slowly thaw and soften at a gradually rising temperature, and the stuffing inside will gradually ripen. Generally, when the dumpling skin is cooked, the stuffing inside is also cooked.
It mainly depends on the steaming time after the water is boiled. Generally, it takes about 15 minutes for frozen jiaozi meat stuffing to steam after the water is boiled, and about 10 minutes for frozen jiaozi meat stuffing.
matters need attention
After the quick-frozen jiaozi is taken out, it doesn't need to be thawed. Just put it on the steamer and steam it for about 15 to 20 minutes. Generally speaking, it takes a short time for jiaozi with vegetarian stuffing, and it is difficult to steam jiaozi with meat stuffing because there is more oil, so it is better to steam it for a few more minutes.
If there is no steamer, you can use a plate of the right size. Put a layer of cooking oil on the plate, then put the jiaozi on it, and put it on a steamer or chopsticks to steam it. The heating efficiency of this steaming method is not as good as that of the steamer, so the steaming time should be lengthened accordingly.
