Rinse berries and remove any twigs, leaves, etc.
Check berries by either freezing for a few hours, poking each berry with a pin, needle or paperclip, or quickly blanching in hot water.
After you've checked your berries, spread them out on your dehydrating trays. Try to put berries of similar size on the same trays.
Turn on your dehydrator to 135 degrees Fahrenheit or the fruit setting if it has one.
Check on your berries or fruit after 12 hours and rotate your trays.
Your fruit is done when it's shriveled and slightly tacky/sticky. Do the "dry test" mentioned in the notes section below.
Store dehydrated berries in an airtight container in a dark cool place for optimal shelf life.
