If you want to stew soup, you should stew it for one and a half to two hours after firing.

Stew is cooked in a water-proof way. Stew the soup so that the raw juice of the raw materials is not moving, clear but not turbid. Stew the soup by blanching the raw materials and removing the fishy smell. Finally, add the auxiliary materials and clean water into the stew pot and cover it. Attention, put it in a large pot, the water in the pot is lower than that in the casserole, so it is advisable not to overflow into the casserole when the water boils.
