It's a hard job to make jiaozi at home, because you have to make both the stuffing and the skin. The most difficult thing to make dumpling stuffing is chopping, which takes a while and requires enough patience. It's okay now. With a blender, you can crush the meat and save some time. I used to think it would take at least half an hour to chop the stuffing. The most difficult thing to make dumpling wrappers is to roll them well. First, knead the dough into strips and then cut it into small pieces. Skilled people can roll the dough into dumpling wrappers quickly, but those who can't roll the dumpling wrappers have to rub the dough into dumpling wrappers by hand, which is also time-consuming.
So when the family used to take care of jiaozi, it was the time when the family got together completely. So many people also make dumpling skins and stuffing separately. People who package jiaozi package jiaozi, and the whole family package it together, so that a delicious jiaozi can be made. But now, when you pack jiaozi, you usually buy the broken stuffing home in advance, and the dumpling wrappers are ready-made. Just pack them yourself when you come back.
