Remove the chocolate shortcrust pastry from the fridge about 10 minutes before processing and knead briefly. Mix the orange zest with the sugar. Roll out the dough between 2 layers of foil to a plate (approx. 35 x 35 cm).
Remove the upper foil. Spread the plate with orange marmalade and sprinkle evenly with the almonds.
With the help of the lower film, roll up firmly from the long side to a roll. Place in a cool place for 1-2 hours. Then brush with water and roll in orange sugar. Cut into about 45 slices. Place on 2 baking trays lined with baking paper.
Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) one after the other for approx. 12 minutes.
