Fill a cocktail shaker with the Vodka, the Cointreau, the cranberry juice and a little bit of lime juice. Add some ice cubes and shake vigorously! Serve the Cosmopolitan cocktail in a traditional cocktail glass. tip: use lightly sweetened cranberry juice instead of regular cranberry juice. This makes the cocktail slightly sweeter and friendlier. Furthermore, Triple Sec can also be used instead of Cointreau.
