step

1. Cut the pig bone into large pieces and wash it for later use.

2. Put the pig bones into the casserole and add water.

3. Wash and peel the wild yam, cut it into blocks, and make it bigger, because yam is easy to crush in the process of making soup.

4. Cut the corn into chunks and wash the carrots.

5. Blanch the pig bones in water, skim off the flesh and blood foam, and pour the corn and carrots into the wok to cook together.

6. After the soup is boiled, after another 30 minutes, the yam will be put into the casserole. The wild yam will be put into the casserole too early, which is easy to be soft and crisp.

7. Put the wild yam into the casserole, stir well and cover it. Cover the casserole and cook for an hour and a half. The soup is rich and attractive.

8. You're done. The soup is rich in color.
