After years of experimenting with sugar-free healthy snacks for our daughter, the one thing she will always eat is dried apple slices. Kids love simplicity.
I used a mandoline to cut four apples into 3-4 mm rounds. Cut them whole with skin on, no need to de-core. Put the slices into a bowl and drizzle with a some lemon juice and mix to stop the apples going brown. Place the slices in one layer on dehydrator trays or baking trays. Sprinkle with cinnamon if desired. Dehydrate between 47-70C for 5-6 hours until crisp. If you're a strict raw foodist only dehydrate up to 47C to not kill the living enzymes. If you're using an oven, turn on to its lowest setting and bake for quite a few hours until you get the chewy or crispy texture you want. Check regularly to avoid burning.
These dried apples are a great lunchbox filler.
Store in an airtight container.
PS, Pear crisps work well too!
