Sift the flour and baking powder onto the work surface. Mix in the hazelnuts, cinnamon, salt and sugar. Put the cold butter on the edge, make a well in the middle and add the egg.
Quickly make a chopped shortcrust pastry from these ingredients. To do this, first chop through the dough with two dough cards and then knead with your hands until a smooth dough is formed. Do not knead longer than necessary, because if the dough becomes too soft, it must first be refrigerated again.
Then roll out the dough thinly (approx. 2 - 3 mm thick) on a floured work surface and cut out round cookies as required. Then place on a prepared baking sheet.
Bake in a preheated oven at 180 ° C top / bottom heat for approx. 7-10 minutes, making sure that the cookies do not get too dark.
In the meantime, heat the jam in the microwave and then strain it through a sieve. Spread about 1 teaspoon of jam on the finished, still warm cookies and glue two halves together.
When they start to set, put the melted couverture in a shallow container and roll through the biscuits once with the edge.
You have to be careful not to dip the cookies too far into the chocolate, otherwise they won`t look so nice afterwards.
Then dip the chocolate rim into the ground hazelnuts. Finally, glue a walnut half on top with a dollop of chocolate and the Kissinger is ready.
