Generally fresh or soaked fungus is recommended to be cooked for 3-5 minutes after the water boils before eating. Fungus should be cooked as thoroughly as possible and eating cooked fungus usually does not cause discomfort. Most of the fungus is dried fungus, which does not have toxins, but if you do not soak the fungus in advance, it will be very difficult to cook, and may not be cooked through, making the texture of the fungus hard, and indigestion and other gastrointestinal symptoms after eating.
