If you are using frozen strawberries or mango, make sure to thaw them before beginning. Cut the mango and strawberries into small cubes and transfer each fruit to a food processor.

Process each fruit separately until it forms a smooth puree. Add 1 tablespoon of lemon juice and 1 teaspoon of honey (adjust the honey to taste) to each mixture, blending well.

Spread the mixtures onto a baking sheet lined with parchment paper, or if using a dehydrator, place them on the drying racks. For a visually appealing effect, pour each fruit puree in separate lines and lightly swirl them together to create a marbled look.

Preheat your oven to 120-140°F (50-60°C). Place the baking sheet in the oven and let the mixture dry for 6-8 hours, depending on the thickness of the layers. Check occasionally until the leather is fully dried and no longer sticky to the touch.

Once the leather is completely dried, remove it from the oven and cut it into squares or strips. Store the leather in an airtight container to keep it fresh.
