Wash the apricots thoroughly under cool water, then halve each one and remove the pit, carefully inspecting and discarding any bruised or damaged spots—these will negatively impact the final flavor and texture of your leather. Arrange the halved apricots cut-side up on a baking sheet and roast at 400°F for 15 minutes until they soften and begin to release their juices. This roasting step concentrates the fruit's natural sugars and makes them easier to blend into a smooth puree. Allow the roasted apricots to cool for about 5 minutes before blending.
Transfer the cooled roasted apricots to a blender and pulse until completely smooth, working in batches if necessary to avoid overfilling. Pour the puree into a large bowl and stir in the cane sugar, fresh lemon juice, and fine sea salt until well combined. The lemon juice adds brightness and helps preserve the fruit leather, while the salt enhances the apricot flavor without making it taste salty. I find that tasting the mixture at this point helps you adjust sweetness if needed—apricots vary in natural sweetness depending on ripeness.
Line a baking sheet with parchment paper and pour the seasoned puree onto it, using an offset spatula or the back of a spoon to spread it evenly to a thickness of 1/8 to 1/4 inch—thinner leather dries faster and more evenly, while thicker leather takes longer but has a chewier texture. If you have sunny, dry weather, you can dry the leather in direct sunlight for 6-12 hours until it's no longer sticky to the touch, turning it occasionally. Alternatively, bake at 200°F for 3 to 3.5 hours, checking periodically—I prefer the oven method for consistency and shorter timing. The leather is ready when it feels dry on the surface but still has a slight pliability; if it becomes too brittle, it was overdried.
Remove the fruit leather from the heat source and let it cool completely to room temperature on the baking sheet—this takes about 30 minutes. Once cooled, gently peel the leather away from the parchment paper, then roll it tightly into a cylinder or cut it into strips, using additional parchment paper between layers to prevent sticking. Store the rolled fruit leather in an airtight container at room temperature for up to 2 weeks, or refrigerate for longer storage.
