Peel persimmons and cut into slices. The thinner the slices, the quicker they are going to dry.

Place the slices ona a baking tray covered with baking paper. Put in a 140 F (60) oven and let dry. You can use a wooden spoon to keep oven door slightly ajar.

I checked them every hour to see how they were doing. I turned them once after about 4 hours. All in all it took 10 hours for my persimmon slices to dry.
