Put flour, sugar, salt, vanilla pulp and ground hazelnuts into a mixing bowl. Add fat in flakes and egg yolk. Mix everything first with the dough hooks, then with your hands to a smooth shortcrust pastry. Wrap in foil and put in the fridge for about 2 hours. Form balls of 2 cm Ø from the dough and place them on a baking tray lined with baking paper.
Use a floured spoon handle to press a small depression into each cookie. Bake in the preheated oven (electric: 200 ° C/ gas: level 3) for 12-15 minutes. Let the cookies cool down on a cake rack, then sieve them with icing sugar. Heat the jelly, stir until smooth and fill the depressions in the cookies with it
