1, not soaked in advance: dried lily is not easy to directly soften and rot, just like dried lotus seeds, it needs to be soaked in advance before cooking.

2, the cooking time is short: the dried lily is usually cooked for 30-60 minutes. If you only cook for a few minutes, it will be basically hard, and it is advisable to continue cooking until it is soft and rotten.

3. Poor quality: A good dried lily should be soft and sweet after cooking. If it tastes hard and bitter, it is related to the poor quality of lilies. You'd better not eat it.
