The method of filling jiaozi with leek is as follows:

1. Wash the leek first, drain the water, and then cut it into small pieces. Then add the right amount of salt and cooking oil and mix well. This can prevent leeks from getting wet.

2. Cut the pork into small pieces, then chop it into mud, and chop it with a knife to make the meat paste taste better. Add pepper water to the meat paste several times and stir until the meat paste is fluffy and tastes better.

3. Mix minced meat and leek thoroughly, and add pepper, soy sauce, soy sauce, thirteen spices, and chicken essence to taste.

4. Finally, wrap it in jiaozi and put it in the refrigerator for freezing, which is very convenient to take with you.

5. Cook jiaozi in the pot, scoop up and control the moisture. If you can't finish it, put it in the refrigerator and freeze it.
