In a blender, combine the ingredients and blend until smooth.
Pour the puree into a small saucepan, bring to a boil, reduce the heat to medium, and let simmer until thickened to an applesauce-like consistency, 15 to 20 minutes.
Let cool, then pour 1 cup of puree per leather in strips on drying sheets set in dehydrator trays. Slap the trays on the counter a couple times to level the liquid. Dehydrate at 125°F (52°C) until the leathers easily peel off the drying sheets, 10 to 12 hours.
Peel the leathers off the sheets and place them on the mesh racks of the dehydrator trays, then place back into the dehydrator for another 2 to 3 hours. Store as directed while warm .
