Preheat the oven to 175 degrees.

Peel and dice the mango flesh, and puree the mango in a food processor until no mango chunks remain and the mixture is a thick liquid.

Line one or two baking sheets with a silicone (silpat) liner. Carefully pour the puree onto the liner and spread it flat with an offset spatula so that it is about 1/8 inch thick all the way around.

Bake in the oven for four hours, or until the fruit leather is no longer sticky/moist to the touch. Remove from oven and place a piece of waxed paper on top of the fruit leather. Then flip the fruit leather over and peel off the silpat liner. Cut the fruit leather (still attached to the waxed paper) into strips for easy rolling or serving.
