Q&A for How to Dry Mushrooms

Yes. There is a wide range of commercial and industrial dehydrators that are not only excellent for drying mushrooms, but as well vegetables, spices, and meat.

Set the dehydrator to run and check back every hour. It normally takes around 2-4 hours before completely drying. Too much drying, though, can make them pretty crunchy.

I don't think the cheese will provide enough liquid to re-hydrate the mushrooms. Try re-hydrating the mushrooms in wine, stock or even water prior to adding them to pizza.

Crack the door open a bit; it will keep the temperature below that lowest setting of 170 degrees.
