10 large Peaches, washed, pitted, and cut in half (I don't peel them)
1/3 C. sugar
In a large saucepan over medium-low heat, cook the peaches and the sugar until the peaches are tender (about 45 minutes). Let it cool a bit.
Meanwhile, prepare your pans. On two sheet pans, roll out heavy-duty plastic wrap (Stretch-tite is best). Spray with a little oil.
Puree the mixture in a blender or food processor until very smooth. With an offset spatula, spread the mixture over the prepared wrap to a thickness of about 1/4" (not too thick, not too thin). Try to spread the peach mixture as evenly as possible to allow for even drying.
Place the pans in an oven on the lowest setting (preferably below 175 degrees). Rotate the pans after a couple hours. May take about six hours to dry thoroughly.
The mixture is enough to make four sheet pans of leather. Store the remainder of the mixture in the refrigerator while the first batch dries.
