Prep your fruit. If using fresh fruit, wash, core/peel as needed, and chop. If using frozen fruit, thaw slightly so it blends easily.
Cook (if necessary). For fruits like apples, pears, or cranberries, simmer with a splash of water for 10–15 minutes until soft. Softer fruits (berries, mango, peaches) can skip cooking.
Blend to a silky purée. Add fruit to a blender with lemon juice and any flavor boosters. Blend until totally smooth. Aim for a thick smoothie consistency.
Reduce excess water (pro tip). If the purée seems thin, simmer in a saucepan over medium-low for 5–8 minutes to thicken. You want it to mound slightly on a spoon.
Preheat and line. Set oven to 170–200°F (75–95°C) or use a dehydrator at 135°F (57°C). Line a rimmed baking sheet with silicone mats or parchment. Silicone works best for easy release.
Spread evenly. Pour purée onto the lined sheet and spread to about 1/8 inch thick. Keep edges slightly thicker—they dry faster. Use an offset spatula for smoothness.
Dry low and slow. Bake 3–6 hours (varies by fruit and oven). Rotate the pan halfway. It's done when the surface is no longer sticky, feels leathery, and lifts cleanly at the edges.
Cool and release. Let it cool completely, then gently peel from the liner. If you hit a sticky patch, return it to the oven for 20–30 more minutes.
Cut and roll. Transfer to a sheet of parchment, cut into strips with a pizza cutter or scissors, then roll them up. Cue instant snack joy.
Optional finishing touch. Dust very lightly with cornstarch if humidity makes them tacky, but usually parchment rolls are enough.
