Blend all of the watermelon chunks in your food processor & place it in a mesh colander lined with paper towels to drain out the excess liquid. You could also use a cheesecloth to strain the liquid. *(3)
If you desire to sweeten your watermelon, place the pureed watermelon back in the blender with your choice of sweeter & blend until the sweetener is evenly dispersed. If need be, place the puree back in the colander one last time to remove any excess liquid.
Evenly spread the watermelon puree onto the center of the baking sheet using a spatula so that it is approximately 1/4 inch thick. *(4)
Bake the Watermelon Fruit Leathers for 6-8 hours, rotating the pan every hour. *(5)
The Watermelon Fruit Leather is done baking when it is no longer shiny & has a matte appearance, it will also no longer be super sticky. *(6)
Let cool completely before removing the Watermelon Fruit Leather from the baking sheet.
Carefully pull the plastic wrap/fruit leather off the baking sheet & flip it onto a piece of parchment paper, fruit leather down. Remove the plastic wrap from the Watermelon Fruit Leather, cut off any excess fruit leather with a pizza cutter, & the excess parchment paper along the long side with clean kitchen scissors.
Cut the fruit leathers/parchment paper into long strips, about an inch wide, & roll them up.
All that’s love is to eat & enjoy! *(7)
I set my oven at 170 degrees F.
It’s best to use a plastic wrap that is microwavable and can tolerate low levels of heat so that it doesn’t melt in the oven and mess up your yummy Watermelon Fruit Leather. Also, make sure the plastic wrap has no ripples when placed on the baking sheet so that the Watermelon Fruit Leather won’t have any weird lines or ripples once it’s baked.
I used a wooden spoon to push the excess watermelon liquid through the colander.
Try to avoid spreading it to the edges of the pan for easy removal.
If you are baking more than one pan at a time making sure to rotate from top to bottom every hour as well as rotating it on the rack.
If your finger doesn’t leave an impression when touching it, & if the fruit leather can be carefully separated from the plastic wrap without easily ripping, then it is done baking.
Keep your Watermelon Fruit Leathers stored in an airtight container for 3-5 days at room temperature or up to a week in the fridge.
