Making your own fruit roll-ups is easy and a good way of using up any tatty or over-ripe fruit left lingering in the fridge or fruit bowl. The prep takes all of 10 seconds although you have to leave the purée in a very low oven to dry out for up to 12 hours so you might want to time the making of it for just before the kids go to bed and then leave it in the oven overnight. Try it first using greaseproof paper - if you think it'll become a regular habit, invest in a silicone baking sheet like this one and peel the hardened fruit off the sheet with professional ease.
Makes 1 baking sheet
1 punnet raspberries or dehulled strawberries
(add 1-2 cored pears if you like)
1 mango (destoned and peeled)
plus 1 handful of dried apricots
Takes 5 minutes + setting
1. Pop whatever fruit combination you're using into a food processor and blitz to a pulp. If you want, you can get the the little ones to push the purée through a sieve with the back of a spoon and remove the berry pips (or keep in if you prefer a bit of texture).
2. Now line a rimmed baking sheet with very lightly oiled greaseproof paper or place your silicone baking sheet on top of a metal one (no oil needed) and pour over your purée. Spread it out with a palette knife and tilt the tray so that it distributes evenly in a uniform layer. It doesn't matter if it doesn't cover the whole sheet - you can neaten it up later with kitchen scissors. Don't spread it too thinly - it'll shrink a bit as it dries out.
3. Bung it in a preheated oven on its lowest setting and leave it overnight (or until completely dried out). You'll need to experiment a bit with drying out times initially as every oven is different. You may find your leather tends to dry out in 4-5 hours so you can just keep checking if you're making it during the day (and if you're making it overnight, don't worry: once it's dry, it won't burn while you're sleeping because the oven isn't that hot).
4. Once dry, peel off the parchment or gently lift the purée off your silicone sheet and snip your fruit leather up with kitchen scissors to your desired width. Your leather will keep in an airtight container for a fortnight, straight or rolled up.
