In a blender, combine the ingredients and blend until smooth, with an applesauce-like consistency.
Pour the puree into a small saucepan, bring to a boil, reduce the heat to medium, and let simmer for 5 minutes to thicken.
Let cool, then 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 drying sheets 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 .
To rehydrate, combine one leather and 1 cup boiling water in a small heatproof bowl and let sit a few minutes. Pour into a blender and process until smooth. Enjoy warm or let cool completely.
