Mushrooms are so rewarding when it comes to dehydrating. Clean them, slice them (optional) and throw them in the warm box for 4-8 hours (around 135 degrees).
If I`m going to turn them into powder, I don`t mind keeping them whole.
If you look carefully below you`ll find Shaeffer helping out by inspecting the proceedings:
If I`m going to use them for something different (the texture of rehydrated mushrooms is almost meaty and awesome in burgers, added to mushroom soup, stuffing or sauces), I like to slice them in the size or shape I intend to use them in. The flavor is concentrated so these taste like uber-mushrooms and I find myself snacking on them too often.
I also find the final result to be so darn pretty that I could stare at gnarly dried mushrooms for hours.
I can`t wait to rehydrate the portabelo slices and have them atop a sandwich or mushroom soup!
