1 large mango, super ripe
First, you need to make sure your mango is SUPER RIPE before you go. I usually wait until they feel super soft and "overripe" to me. It will feel softer than a peach.
1) Take the mango and cut lengthwise down each side of the pit to make 3 pieces. Take the side pieces and make 1/4 inch slices. At this point I remove the skin by running a thin knife around the edge of each slice (this is easy because the ripe mango cuts smoothly).
2) Arrange in your dehydrator and dry overnight at 110 degrees Fahrenheit. In the morning, check. They should be leathery. If they need more drying, flip them over and let dry a few more hours. Depending on the dehydrator you use the time might vary.
