Step 2: When jiaozi's dough is rolled, add salt to adjust the stuffing, mix well and cook it as soon as possible, so that the water in the leek will be less killed.
Step 3: Cook jiaozi once. Just cook a thin layer of dumpling skin, turn off the fire and serve quickly. The leek cooked in this way is slightly raw and just delicious. You can eat it raw, not cooked for a long time.
