Any ripe fruit (apples, peaches, berries, etc.)
Sm. amount of water

Mix fruit and water in blender. Add ripe banana if too tart. Should be thick. Line flat pan with plastic wrap. Pour fruit into pan and spread to 1/4 inch thickness. Place in warm oven (125 degrees) with oven door slightly ajar.

When you can pick it up and remove it from the plastic, it is dry enough (about 12 hours). Cut into squares, or roll up, or tear off.
