If ordinary frozen dumplings are used to make fried dumplings, of course, they must be cooked first. Just like cooking jiaozi, they should be cooked in boiling water in a pot with medium fire, which usually takes about 5 minutes. When jiaozi comes to the surface, it is cooked. When making fried dumplings, it is usually done with cold jiaozi overnight. It is easy to fry the hot jiaozi that has just come out of the pot. It is best to let it cool, or rinse it with cold water before frying.

There are, of course, those who sell Japanese-style long fried dumplings, which don't need to be cooked. Add a little jiaozi frozen on the oil code to the pan and fry for about 2 minutes on medium heat. Pour half a cup of water on the lid for about 2 minutes, open the lid and wait for the water to boil, then shovel it up and put it on the plate to eat.
