Wash the pork belly first, turn out the inside of the pork belly, add a proper amount of flour, grab it evenly, wash it with water, add salt and vinegar, grab it evenly, and marinate for five minutes. However, after repeated washing with clear water for several times, the pig's belly can be cleaned very cleanly. The specific method is as follows:

Ingredients: pork tripe, flour, salt, white vinegar and water.

1, first cut a small hole in the pig's belly, turn out the inner surface, and scrape off the residue with a knife or nails.

2. Sprinkle flour on the surface of the pork belly, so that the pork belly is completely covered with flour, especially the folds of the pork belly, where there is a lot of gastric juice, so be sure to sprinkle enough flour. Cover all the pork bellies.

3. Keep rubbing with your hands, and then rub the surface of the pork belly again to make the gastric juice and impurities stick to the flour.

4. Remove the flour from the pork belly and rinse it with clear water.

5, put the pork belly in the basin, add salt and vinegar, evenly spread it inside and on the surface of the pork belly, both inside and outside, and leave it for a few minutes.

6. Wash the inside and outside of the pig's belly with your hands, and rinse it several times with clear water.

7. Clean pork belly as shown in the figure.

Precautions: Wash pork bellies with flour, which is sticky when wet. Using this feature of flour, the gastric juice and impurities in pork bellies can be removed very cleanly, and salt and vinegar can sterilize and remove odor. Combining these three materials and cleaning methods, the pork bellies can be cleaned very cleanly.
