Make a kneading dough from sifted flour mixed with baking powder, sugar, egg, cocoa, cinnamon, margarine and red wine. Let rest for an hour in the cold.
Then roll out thinly and cut out round cookies. Bake at 180 ° for about 10 minutes. Let cool down well.
Then spread jam on the underside of each cookie and put a second cookie together. Brush the edge of the pastry with melted chocolate icing and roll immediately in the ground nuts.
