Put flour, almonds, sugar, egg, spices and salt in a mixing bowl. Add the fat in pieces and mix in with the dough hooks of the hand mixer. Then knead into a smooth dough with cool hands.
Cover and leave to rest in the refrigerator for at least 2 hours. Roll out the dough on a lightly floured work surface to a thickness of approx. 5 mm and cut into 2 x 10 cm long strips. Turn the strips into a spiral and place them on two baking trays lined with baking paper.
Sprinkle the spirals with almond flakes and bake in a preheated oven (electric range: 175 °C/ gas: level 2) for approx. 14 minutes until golden brown. Let them cool down on a cake rack. Dust with icing sugar.
