Dehydrated coconut makes a nice chewy, squeaky snack. If you dehydrate a little further, it becomes quite crunchy. By making it yourself, you can avoid the bleach and preservatives that are used in commercial production.
Remove liquid from the coconut before breaking it apart. Find a soft eye and push a screwdriver through to the center and drain liquid
Tap the seam the runs between the eyes to break apart & remove outer shell
Use a potato peeler to peell off the inner husk
Cut into 1/4 - 3/8 inch slices
Place on dehydrator trays
Dehydrate at 130° for 8 - 10 hours until dry
