You will need a cocktail shaker for this one!
Fill the cocktail shaker with ice.
Squeeze your lime and add 10 ml of the juice into the cocktail shaker.
Next add Smirnoff, Cointreau and cranberry juice into the shaker.
Shake vigorously for 30 seconds until cold and well blended.
Drain your shaken Cosmo into a martini glass and serve with a lime wheel.
