After the tremella soup is sealed and stored in the refrigerator, it can be eaten the next day. Cook more tremella soup at a time, divide it into small portions and keep it in the refrigerator. Take out each serving and heat it once, and you can keep it for 1-2 days, so don't worry at all. If the tremella is soaked too much at one time, just put it in the refrigerator to avoid stale and smelly, and it can still be cooked and eaten the next day.
