The subject wants to ask, "Does Supor need to replenish water in the process of using water-insulated stew?" No need. According to Sina Entertainment Network, adding water to Supor water-proof stew will reduce the temperature and affect the stew. It takes a long time to boil the soup, and the heat can be transferred to all parts of the pot smoothly. It is most suitable for professional Supor's waterproof stew, casserole or waterproof stew.
