Dessert

Preheat the oven to 400°F.
Whip the egg whites, gradually adding the caster sugar, until very stiff.
Quickly beat in the egg yolks, lemon zest, and vanilla sugar without beating too hard.
Carefully fold the flour into the mixture.
Butter two oven-proof dishes and optionally line the bottoms with jam or custard.
Heap three large dollops of the egg mass into the dish, slightly offset to form three 'mountains'.
Bake for 10 minutes until the Nockerl are slightly brown on top.
