Tschunk

Originating from Germany, Tschunk is a cocktail made with a combination of rum (white or dark), brown sugar, crushed ice, lime cubes, and Club-Mate – a caffeinated, carbonated German beverage based on mate-extract. In order to prepare it, chopped limes and brown sugar are first squashed in a highball glass, while crushed ice, rum, and Club-Mate are added in the end.
