Orange Bites

Separate the eggs and set the egg whites aside.

Quickly knead the flour, egg yolks, diced butter, salt, sugar and finely grated lemon zest into a smooth dough.

Press the dough into a flat disk, wrap it and chill in the refrigerator for about 30 minutes.

Preheat the oven: fan 150 °C (conventional oven 175 °C). Line a baking tray with parchment paper.

Finely grate the orange peel and juice the oranges. Measure out 100 ml of orange juice.

Roll the dough into a rectangle on the prepared baking tray.

Whip the egg whites until stiff. Gently fold in 100 ml orange juice, orange zest, ground almonds, 3 tbsp sugar and vanilla sugar.

Spread the orange-almond mixture evenly over the dough.

Bake in the preheated oven for about 25 minutes, until the surface is lightly golden.

Cut into pieces while still hot and let cool on a rack.

Decorate with melted chocolate if desired.
