In a blender, combine the ingredients, starting with 1/2 cup water, andblend until smooth; add more water if needed to get the proper applesauce-like consistency.
Pour the puree into a small saucepan, bring to a boil, reduce the heat to medium, and let simmer for 2 minutes.
Let cool, then pour 1 cup of puree per leather in 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 drying sheet and place them on the mesh rack of the dehydrator tray itself, then place back into the dehydrator for another 2 to 3 hours. Store as directed while warm .
