The water temperature for soaking mushrooms is low. For example, if cold water is used, it will take 6 to 1 hours. If you plan to use it the next day, you can soak it before going to bed the night before, and the mushrooms will be soaked in the morning.
if you choose to soak mushrooms in hot water, the time will be relatively shorter, and it usually takes only half an hour or an hour to soak them completely.
