Fruit roll-ups are great for picnics, big walks or school lunches. The general idea is to cook down any fruit and lightly sweeten it with a little sugar or honey, then blitz it to a smooth purée and dehydrate it in a low oven.
Combine the plums, cinnamon and sugar in a saucepan.
Cook over medium heat, stirring, for 15–20 minutes or until soft and collapsed.
Set aside to cool to room temperature.
Transfer the mixture to a food processor or blender and then blitz it to a smooth purée.
Spread the purée in a thin layer on baking trays lined with baking paper, and pop them into a very, very low oven – 75°C (170°F) if yours goes down that low – overnight or until completely dehydrated.
Cut the fruit sheets into strips, place them on baking paper and roll them up into cute little bundles.
These will last for a few weeks in a jar or in an airtight container.
