If you're using fresh fruit, wash and prep. Cut them into chunks for easier blending. For frozen fruit, simply let it thaw slightly before blending. You can use a variety of fruits based on what’s in season or what you have in your freezer.
Add the fruit chunks into a high-speed blender. Pour in the lemon juice and honey or sugar. Blend on high until smooth. If the mixture seems too thick, you can add a little water to help it blend more easily, but aim for a thick, puree-like consistency.
Line your dehydrator trays with parchment paper or silicone mats. If you have the silicone mats with raised edges, they work wonderfully to prevent the fruit from spilling over. Pour the fruit puree evenly onto the trays, spreading it into a thin, uniform layer. The thinner you spread it, the quicker it will dry, but don’t go too thin, or it might crack when rolling. See note below for using an oven.
Set your dehydrator to 135°F. Let it dry for about 5 hours, or until the fruit leather feels dry to the touch but still has a bit of flexibility. It should be tacky but not sticky. Keep an eye on it towards the end to avoid over-drying.
Once the fruit leather is completely dried, remove it from the dehydrator and let it cool. Cut it into strips with a sharp knife or kitchen scissors. Roll each strip up in parchment paper, and store them in an airtight jar or container. Keep them at room temperature for up to 2 weeks.
