1. If you don't eat the bought auricularia auricula for a long time, don't keep it in a food bag, because auricularia auricula is easy to absorb water and deteriorate. The first step is to lay a layer of clean paper under it, the kind of roast duck. Then put the fungus in the carton, and then put the carton in the refrigerator. If there is no refrigerator, put it in a cool and dry place.

2. If it is not stored properly and tastes bad, if it is not serious, it can be brewed with boiling water first and then soaked with cold water. If it is serious, don't eat it.
