Dehydrated mushrooms have many uses: in stews, soups, and other dishes, or as a great way to carry food on a backpacking trip. Here is an easy way to make them if you have a dehydrator. If you don't have one, I highly recommend getting one! I got mine used from Craigslist.
- Clean the mushrooms. Do so with a brush, ideally.
- Slice the mushrooms.
- Place slices on dehydrator tray.
- Dehydrate on low heat (below 115 degrees, preferably, for maximum retained nutrient value) for up to 8 hours - that's how long mine took. Mushrooms that aren't as thick as portabellos will need shorter times, so be sure to check. They should be light and dry when they are done.
- Store in an airtight container. I use glass because it's moth-proof and, well, not plastic.
