1. Ingredients: 3 portions of meaty bones, appropriate amount of kelp, 1 section of lotus root, appropriate amount of ginger, and appropriate amount of pepper.

2. First peel the lotus root and cut into cubes for later use. Soak the kelp in advance, wash it and cut it for later use.

3. For pork bones with meat, you can use pork ribs or tube bones, rinse them with clean water, and then boil them in cold water.

4. Slice the ginger and throw it into the casserole.

5. After the fire comes to a boil, skim off the foam on top and continue cooking over medium-low heat.

6. After about half an hour, throw in the kelp and lotus root. Cover the lid and simmer for 2 hours. If the soup is not enough during this period, you can add a little boiling water.

7. Done, both kelp and lotus root are very soft.
