You'll need a wire mesh screen. First cut the wire mesh screen small enough to fit in the oven but large enough to hold the mushrooms you plan on drying. Next place the mushrooms on top of the screen with enough room between each amanita for air to vent. Now place the screen into the oven, with the door of the oven open slightly. Set your oven to bake at the lowest temperature possible. Leave them in for about an hour, then remove them along with the screen. Allow them to cool at room temperature, if you want to save some place them in a sealed bag. Now you can smoke or eat them. Have fun, be safe.
