My trays are lined with wire mesh screen I purchased from the local hardware store and cut to fit.
This is what they looked like after 24 hours:
And this is the final result:
#1 mushrooms dried to 1 cup. A tight fit in a jelly jar.
I dried some the next morning. I rehydrated about 4 T of the dried mushrooms in hot water for about ten minutes then added them to my egg scramble. Perfect!
Now that I know this works well, I'm going to buy a larger quantity at Sam's Club and get a bunch of them put into jars.
Have you tried dehydrating mushrooms? Do you find a difference between varieties? I'd love to hear your thoughts.
