Separate eggs. Whisk the egg yolks and 60 g sugar with the whisks of the mixer until white and creamy. Add milk while stirring. Add orange liqueur to taste, orange and lemon peel. Stir in the flour and allow to swell for approx. 10 minutes.
Beat the egg whites until very stiff and allow 40 g sugar to trickle in. Fold the beaten egg whites into the dough.
Heat half of the butter in a large pan. Add half of the dough and bake at medium heat from the bottom side until golden brown. Turn with the help of a large pallet, allow to rise briefly.
Then pluck the dough into pieces with two forks and fry them all around until golden brown. Place in a hot oven (at 50 °C). Bake another Kaiserschmarrn with the remaining dough.
Dust Kaiserschmarrn thickly with icing sugar. This is accompanied by apple compote, red fruit jelly, cranberry cream, vanilla and chocolate ice cream.
