For the orange tarts, knead shortcrust pastry from ingredients.
Leave to cool for 30 minutes. Roll out the dough about 5 mm thick and cut out jagged slices, bake in the oven at150°.
After cooling, spread orange marmalade on 2 slices each and assemble. Draw threads of chocolate icing over the tartlets, sprinkle aranzini and decorate with sugar icing (about 6 dag powdered sugar and lemon juice).
Serve the orange tartlets.
