It takes about an hour to stew, and the best time is only half an hour if it is only cooked. It is recommended to stew for about an hour.

Half an hour to an hour is the best. If it is bone soup or pig's trotters soup, the time can be appropriately extended, but it should not exceed 3 hours. The longer the soup is cooked, the more vitamin C in vegetables and vitamin B 1 in meat are lost, which is not good for nutrition.

Specific practices:

1. Material: a catty of ribs, ginger slices, peppers, cinnamon, star anise, pepper, salt and chicken essence.

2. Wash the ribs, blanch them in boiling water, and then wash them with cold water for later use.

3. Put the spareribs in electricity, then add wax gourd, star anise, cinnamon, ginger slices and pepper, then add seasoning, a little salt (try the salty taste soon, you can add salt again), chicken essence, pepper and vinegar.

4. Add water (just over the bone), boil over high fire, and simmer for 2 to 3 hours after 2 minutes. Some electric cookers have automatic function, so after adding water, the rest will be handed over to the electric cooker. It's as simple as making ribs and stewed melon in the electric cooker.
