Steps:

1. The pork leg bones bought from outside can be chopped from the middle, which is more convenient to stew, and it is easy to suck the bone marrow in the middle with a straw. First, clean the floating ash, broken bone residue and pig blood on the surface with clear water.

2. Add water. If you like soup, you can add it to the MAX beside the pot. If you want to make the soup rich, just touch the top of the bone gently.

3. According to personal taste, add appropriate amount of onion, ginger and salt. If you like star anise, you can also add a slice of star anise, a few peppers and fragrant leaves.

4. Put it into the pressure cooker, cover it, and turn the lock to prevent the soup from overflowing due to excessive pressure when stewing the soup. Before cooking soup, you can soak the bone with seasoning and water for 2 hours, so that the seasoning can fully enter the bone, which will be more delicious. After two hours, turn the pressure cooker to the ribs button, and then the cooker will stop automatically.

5. The pressure cooker deflates automatically, so you can put the soup and bones in the bowl, and the delicious pig bone soup will be cooked. The bones stewed in the pressure cooker are not so strong, the bone marrow is easier to suck out and the soup is rich.
