Step 1

Start with fresh mushrooms (this method will not work with mushrooms past their prime), and wipe them clean with a lightly dampened towel. Do NOT wash them under running water.

Step 2

Transfer them to a container that allows air to circulate around them, such as a mesh colander, or a baking rack set on top of a baking sheet. Do not overcrowd the mushrooms.

Step 3

Place them in a well ventilated area (any area of the house with a ready supply of fresh air), preferably in the sun if possible. Allow them to air dry for 7-10 days, until they do not give when squeezed. Drying time will vary based on humidity levels and the size of the mushrooms.

Step 4

To expedite the process, you can partially dehydrate them in the oven before air drying. Place in an oven heated to 175 degrees F/80 degrees C for 2 hours, flipping them halfway through. Then transfer to a colander to air-dry for another 3-5 days.

Step 5

Store them in a sealed container for up to 2 years (be sure the mushrooms are COMPLETELY dried before sealing them away).
