Step 1

Preheat oven to 400° F.

Step 2

Wash, cut in half and pit the plums. Lay halved plums out on rimmed cookie sheets with cut side up and place in the oven for 20 min. Check every 5 minutes to avoid burning the plums.

Step 3

After 20 minutes, remove plums from the oven and let them cool. Using blade attachment in the food processor, blend plums until smooth and pour finished mixture into a large bowl.

Step 4

Add 3/4 cup sugar to blended plums and stir well. Add more sugar to taste if needed. Than line rimmed baking sheet with parchment paper covering the walls of the baking sheet as well. Pour the purée in to about an 1/8" to 1/4" thickness.

Step 5

Let dry in the oven for as long as it takes for the purée to dry out and form fruit leather, about 6-8 hours, more or less depending on the thickness of your fruit leather.

Step 6

Heat the oven to low 140°F. Place the baking sheets with purée in the oven on the two racks placed as much in the center as possible.

Step 7

If the lowest setting on the oven is 170°F, than preheat to 170°. Turn the oven off and leave the door closed completely and reheat it after an hour; repeat as necessary until it dries out. The fruit leather is ready when it is no longer sticky and has a smooth surface.
