Hokto’s mushrooms do not need to be washed. Our mushrooms are grown without any agrichemicals and in automated facilities that does not basically require human contacts. If you still hesitate to cook them without washing, you can wipe the mushroom or wash them lightly.
Also, washing mushrooms will wash away majority of beneficial nutrition that are water soluble and will lose the texture and flavors. Again, you don’t have to wash mushrooms if they are from Hokto.
