In fact, jiaozi Pippi has soft and hard skills. First of all. It is best to mend the noodles the night before. Put it in the refrigerator. Refrigerate overnight and reuse it the next day. I'm sure it's soft. If it's cold, you can keep the noodles at room temperature. Second. Some people like to add less salt when mixing flour, which can increase flour. It is best to use Jinxin, which is suitable to be mixed with jiaozi powder. Others say that it tastes a little bad if you refuel.
