- You can do this with oranges, lemons, apples...
Preheat your oven to 140°C/275°F/gas 1 and line some baking trays with greaseproof paper/parchment.
Slice your fruit of choice very thinly. For consistency use a mandolin. Arrange the slices on the trays, then bake for 45 minutes to 1 hour, turning halfway through cooking, until completely dried out. Leave to cool.
