In a cup, press 3-4 blueberries and 2-3 raspberries and then fill the cup with crushed ice. Now add 4 cl Taunus-Tropfen, about half a lemon (squeezed) and a tablespoon of sugar and stir well. Finally, place two sprigs of mint in the cup (press lightly beforehand, so that the aroma unfolds a bit) and let it rest for a moment.
