1. Ingredients: 400 grams of pork chop, one carrot, six water chestnuts, one yam (yam), and a small piece of ginger.

2. Chop the ribs into pieces first. You can chop them into larger pieces when making soup.

3. Put the ribs in a pot and cook to remove the blood foam.

4. Take it out, control the water, and put it in a pressure cooker for fifteen minutes. If it is a pot specially made for soup, it will need to cook for about an hour, so you need to add more ribs.

5. Now let’s deal with the ingredients. Peel the yam and cut it into pieces, peel and wash the water chestnuts, peel and cut the carrots into pieces, and put them in a bowl for later use.

6. When the ribs are almost cooked, put down all the ingredients, add a spoonful of salt, and simmer for another fifteen minutes.

7. When the time is up, don’t rush to open the lid. Wait until the water vapor in the pressure cooker has finished coming out before opening it.
