It is not recommended to eat shiitake mushrooms if they have been soaked for more than two days, they need to be soaked before eating because they taste better after soaking. If the mushrooms are a little moldy, but the inside is not spoiled, you can put the moldy mushrooms under the sun.

When exposed to the sun to remove the mold spots can still be eaten, but mold is more serious, it is not recommended to eat. The shiitake mushrooms we are talking about are actually winter mushrooms, which are smaller in size, and under normal circumstances, the soaking time is around 8 to 12 hours. Generally, cool water is used for soaking, and it can be soaked well one night in advance.
