In a blender, combine the ingredients and blend until smooth, with an applesauce-like consistency.
Pour 1 cup of puree per leather into strips on a drying sheet set in a dehydrator tray. Slap the tray on the counter a couple times to level the liquid. Dehydrate at 125°F (52°C) until the leathers easily peel off the drying sheet, 10 to 12 hours.
Peel the leathers off the sheet and place them on the mesh rack of the dehydrator tray, then place back into the dehydrator for another 2 to 3 hours. This leather will be brittle.
