Don't cook frozen jiaozi until the water boils. Jiaozi is frozen inside and cooked outside, and the dough is cooked quickly. However, when the heat from the dough enters the frozen vegetable stuffing, on the one hand, it is difficult to cook the meat stuffing, on the other hand, it is difficult to cook and takes a long time. Therefore, before the filling is ready, the dough is often boiled. Jiaozi cooked in this way is not only ugly and unpalatable, but also unsanitary. ?

Frozen jiaozi is frozen under cold water, and frozen jiaozi is heated with cold water. When the water temperature rises slowly, the temperature of dough and stuffing also rises slowly. When the water is boiling, the temperature inside, outside and boiling water in jiaozi is very uniform, so the boiled jiaozi is elastic, cooked, safe, hygienic and delicious.

Quick-frozen jiaozi is a kind of food that can be eaten at any time after the wrapped jiaozi is quickly frozen. Jiaozi is a traditional special food loved by the Han people in China, and it is a must-eat food during the Spring Festival every year.

According to legend, jiaozi was first invented by Zhang Zhongjing, a doctor in Nanyang, Henan Province during the Eastern Han Dynasty in China. In many provinces and cities in China, there is also the habit of eating jiaozi on the solstice in winter.
