Wash, peel and remove seed from each mango.
Slice or cube mango as desired. I purchased ready-to-serve mango from Costco which made it a lot easier for me to prep them.
Space them so they are not touching each other on your dehydrator racks.
I set my Excalibur Dehydrator at (135°F) = 57°C) degrees and these took about 7 hours today.
Please check your own dehydrator to see the correct temperature for your machine.
The time to dehydrate will always depend on the humidity in the room. I stopped drying them when they were still a little pliable, but not brittle.
I store them in mason jars using a FoodSaver to remove the air.
