Purée ingredients in blender. To oven dry: Heat oven to 150°. Spread puréed fruit 1/4 inch thick in approximately 10 x 15-inch jelly-roll pans which have been boiled very lightly or sprayed with vegetable coating. Bake for 10 to 12 hours. Test for doneness by pulling up leather at corners. If it sticks to pan, continue baking. When done, it should be smooth and glossy underneath and should peel off of pan in a continuous sheet. Leather will be about 1/8 to 1/16 inch thick. Roll up like a jelly roll while still warm and pliable. Leather will roll more easily if sprinkled with powdered sugar. Cut into pinwheels with kitchen shears. Baking time will vary according to type and consistency of fruit pulp, thickness of layer, etc. Open oven door every few hours to let moisture escape. Wrap in plastic wrap and store in cool dry place. Will keep 3 to 4 weeks. To sun dry: Place pans outside when temperature is about 85°, humidity less than 60%. Cover with glass. Takes 2 to 3 days.
