Roast the almonds in a pan without fat until golden brown, take them out and let them cool down. Then mix with flour, icing sugar, hazelnuts, cinnamon and chilli. Knead with butter, egg yolk and salt to a smooth dough. Wrap in foil and put in a cool place for about 30 minutes. Shape the dough into croissants and refrigerate for another 30 minutes.
Then place on a baking tray lined with baking paper. Bake in a preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for approx. 10 minutes and let cool down. Temper glazes according to package instructions. Coat the croissants with the glaze, allow to dry and decorate with decorative lettering
