Another modern classic is the cosmopolitan which features citrus vodka (also known as vodka citron) and cranberry juice, along with a touch of triple sec (the official recipe calls for Cointreau, but any quality triple sec will do the job!) This cocktail should be served in a cocktail glass and can be garnished with a slice of lime to decorate.
Classic Cosmopolitan - I make these by the pitcher full. 10 oz vodka; 8 ounces triple sec, 5 ounces Rose's Sweeetened lime juice and 10 ounces of cranberry juice. (You can add a little less vodka, but why?)
