Fill a cocktail shaker with ice then add vodka, triple sec, cranberry juice and lime juice. (We like the extra bite of extra lime juice, so we use 1/2 an ounce in our cosmopolitan cocktails. However, use what is best for your taste). Shake the cocktail shaker for about 30 seconds until well chilled. Then, strain into a martini glass.

Garnish with orange peel/twist. For an extra burst of flavor, peel the orange twist over the filled cocktail glass. This way, the orange oils spray into the glass.
