Preheat oven to 75c/265f fan-forced.
Add fruit to a blender and blend until completely smooth.
Line a baking tray with baking paper or a silicone baking mat.
Pour mixture onto tray and spread evenly.For thinner roll-ups: spread to around 2mm thick and bake 3–4 hours.For thicker, chewier roll-ups: spread to around 4mm thick and bake 4.5–6.5 hours. Bake until dry to touch and no longer tacky, but still flexible. Avoid overbaking - crispy edges mean they’ve gone too far.
Cool completely, then slice into strips and roll up.
Store in an airtight container at room temperature for up to 4 weeks or freeze for up to 6 months.
