Begin by peeling your apples, then place them on their side and slice them into 5-10cm thick rings. Cut the core piece out of the centre then drip a couple of drops of lemon juice over them and spread with your fingers to stop them oxidising and going brown. Now sieve the gluten free flour into a bowl, add the oat milk and a couple of twists of salt. Separate the egg white into a separate bowl then add the egg yolk to the flour mix. Use a hand mixer to beat the egg white until stiff, then mix the flour mixture together before folding in the egg whites to form the batter. Now you are ready to cook.

In a frying pan, heat the oil until hot then reduce the heat to medium. Dip the apple rings into the batter to coat then place into the hot frying pan and leave to fry for around a minute before flipping. Fry again for a minute and repeat until you have cooked both sides for around 2 minutes or the batter is golden brown. When done, place onto kitchen paper to catch some of the oil before placing on a plate. Mix the sugar and cinnamon together then add a teaspoon to the top of the apples rings and serve.
