knead almonds, 275 g flour, sugar, egg yolk, butter in pieces and 1 pinch of salt first with the dough hooks of the mixer, then quickly with your hands to a smooth dough
Form dough into a ball, wrap in foil and chill for about 1 hour. Line two baking trays with baking paper. Preheat oven (electric cooker: 200 °C/circulating air: 175 °C/gas: level 3)
Form the dough into 3-4 rolls (1.5 cm Ø each) on a floured work surface. Cut each into 16-18 small pieces (each approx. 3 cm long)
Form individual pieces of dough into rolls of approx. 8 cm in length and bend them into croissants, forming the dough pieces into crescents and pressing the ends together at a point
Bake the croissants in a hot oven for 10-12 minutes until they are brown. Sieve the icing sugar onto a flat plate and mix with vanilla sugar. Turn the croissants individually while still hot. Let them cool down
