Peel the apples and cut out the core. Then cut the apples into 1cm thick rings.
Drizzle the apple rings with lemon juice and sprinkle a thin layer of sugar.
Separate eggs into yolks and whites. Beat the egg whites with the mixer until stiff.
Put the two egg yolks, flour, cornstarch, butter, salt, remaining sugar, milk and cream in a bowl and mix everything together. Then carefully fold in the stiffly beaten egg whites.
Dip the apple rings into the batter and fry in hot oil/fat in a pan until golden.
Sprinkle the finished rings with cinnamon and sugar and serve warm.
