Dump your dried ’shrooms in the food processor and pulse a few times to chop them up uniformly. If the lid of your food processor isn’t on tight, a fine mist of mushroom dust will erupt from the crack, so check the seal before you continue blitzing.
Next, turn the processor on for 2 minutes or as long as it takes for the mushrooms to break down into a fine powder. (If you use a super-charged blender like a Vitamix, you’ll finish in less time.)
In a large bowl, combine the powdered mushrooms, salt, red pepper flakes, dried thyme, and freshly cracked black pepper. Stir well to mix thoroughly. Once the red pepper flakes are evenly distributed, you’re all set!
Scoop out a scant ⅓ cup of the Magic Mushroom Powder, and place it on a piece of parchment paper. Pull up the sides of the parchment and use it as a funnel to transfer the seasoning salt into each jar.
Warning: Do not open the container immediately after switching off your processor. A mushroom cloud will literally explode out of the top and you’ll find yourself coughing up Magic Mushroom Powder for the next few minutes. Instead, be patient and let the powder settle before you open it.
