Homemade Fruit Roll-ups

Place parchment paper on a jelly roll pan , allowing 1/2" overhang on all sides. Smooth 1 jar of applesauce out onto the parchment, not going directly to the edges. Bake in a 170 degree oven for 8-10 hours, or until the edges and middle are set. Do watch because once the leather starts to dry it can get tough.
