Make these with your kids – it’s fun! They are naturally sweet, crispy snacks that can be eaten on the go or at home any time of the day. It’s always worth making a large batch as you’d be surprised how quickly these get eaten!
Combine the lemon juice in a bowl with the water. Core the apple (an apple corer will come in handy for this if you have one) and slice the apples thinly – no thicker than 2-3mm. Soak them in the lemon water for approximately 30 minutes. Drain the slices and pat dry with clean kitchen towels. Lay on dehydrator trays in single layers ensuring no pieces are touching. Set the temperature to a low heat – 55C/130F – and leave overnight.
If you only have an oven, then place the apples on a large baking tray instead and cook in oven at 90C/195F for 1 hour. Turn the apples over and bake for a further 1-2 hours (depending on how crispy you would like them). Check periodically and reduce or increase the cooking time accordingly. Once done, allow to cool and then store in airtight container in fridge for up to 1 month.
