The whole apples are peeled and cored with the cutter and cut into finger-thick slices. Sprinkle with sugar and drizzle with kirsch. Let it steep for an hour.
Baking dough: Mix the remaining ingredients into a smooth dough and then pull in the egg whites.
Completion: Turn the apple slices in the batter and bake in the hot clarified butter until golden brown. Sprinkle with cinnamon and sugar.
Sour cream: soak gelatine in cold water. Whip the sour cream with sugar, vanilla pulp and lemon zest until creamy. Put a cup aside and heat it up. Dissolve the gelatine in it and pour the kirsch into the remaining sour cream.
