Soak the ribs in clear water, wash them and cut them into small pieces, then add enough clear water. It's best not to add water in the soup.

After boiling, skim off the froth. Because most of the blood has been removed from the ribs before soaking, there is not much floating foam, so it is easy to remove and add ginger and change it into a small fire.

Pour a few drops of vinegar into the pot, which can not only remove the fishy smell, but also promote the decomposition of calcium, but don't put salt in a hurry, otherwise the ribs will be tight; Soak kelp silk in cold water until soft and clean;

Stew the ribs on low heat for 30 to 40 minutes, then add the kelp. You can add salt to taste at this time. After stewing for half an hour, add the chopped wax gourd and stew for another 20 minutes until the wax gourd becomes soft.
