Vinegar can be added to the pork ribs and lotus root soup. The specific method is as follows:

Ingredients: spare ribs (about 700g), 2 sections of lotus root, 1 piece of ginger

Method:

1. Brush the ginger clean, peel and slice. Put the ginger peel and the pork ribs into a pot of water. After boiling, continue to cook for three to four minutes. Remove the ribs and drain them. Discard the water and ginger peel and don't use them!

2. Put the blanched pork ribs and ginger slices into a casserole, and add enough water to cover the pork ribs and be slightly higher than 1cm. ——Because a small amount of water will be lost during the soup making process, the water must be added at one time.

3. After boiling, cover and simmer over low heat for about 1 hour.

4. Peel the lotus root, cut into hob pieces, sprinkle with a little salt, and kill it - that is, mix well with salt and marinate for about 10 minutes.

5. Put the lotus root into the soup pot and continue to simmer for 1 hour.

6. When the meat is rotten and the lotus root starch is cooked, add an appropriate amount of salt, turn to medium heat and boil for about 10 minutes, then sprinkle with chopped green onion.
