In a separate bowl, whisk the 3 egg whites to soft peaks and set aside.

Fold the lemon zest and peeled, chopped cooking apples into the main mixture.

Sift in the plain flour, salt, cinnamon, baking powder and bicarbonate of soda. Fold into the wet mixture until just combined.

Gently fold in the whisked egg whites.

Pour into the prepared tin and bake at 160°C for 1 hour 30 minutes until a skewer comes out clean.
