Scrub all citrus very well with a green nylon scrubber. Slice off north and south ends to the meat of the fruit.
I used my Cuisanart with thick slice blade(use force to slice when machine is turned on to get full slices) but you can slice them with a big sharp knife. They need to ber sliced very thin but not so thin they fall apart.
After all have been sliced, place in a large bowl a few at a time in cane sugar and coat well. Place with out over lapping in the dehydrator trays and turn it on with one empty tray at the top.
I dehydrated for 2 1/2 day and switched trays around once a day. When they look dry, turn off machine and let set over night in a cool place. Use a spatula to remove from trays and seal in a zip lock back and store in frig or very cool place. Enjoy!
