Dehydrated shredded coconut takes a little more work that just buying commercial shredded coconut. On the other hand, it's not sweetened, bleached or pasteurized!
Remove liquid from the coconut before breaking it apart. To do this, find a soft eye and push a screwdriver through to the center, then drain liquid
Tap the seam the runs between the eyes to break apart & remove outer shell
Use a potato peeler to peel off the inner husk
Use a grater to shred coconut pieces
To keep coconut from falling through trays, place on Plastic-Mesh Dehydrator Screens on the dehydrator trays. You may also want to put a Fruit Roll-Up Sheet on an empty tray at the bottom of all trays to catch any stray pieces.
Dehydrate at 115° for 2 - 4 hours until dry
