Put flour, crème fraîche and butter in flakes in a mixing bowl. First knead with the dough hooks of the hand mixer, then with cool hands quickly to a smooth dough. Roll out the dough to a thickness of approx. 5 mm on a work surface dusted well with flour. Cut out curls with a rogue cookie cutter (approx. 5.5 cm). Place on 3 baking trays lined with baking paper. Bake one after the other in a preheated oven (electric range: 175 °C/ convection oven: 150 °C/ gas: level 2) for 15-20 minutes.
Let them cool down. Mix icing sugar and liqueur to a smooth glaze. Spread the mixture on the curls. Sprinkle with sugar crystals and sugar pearls. Leave to dry
