1 1/2 oz of Grey Goose L'orange Vodka
1 oz of Cranberry Juice
3/4 oz of cointreau orange liqueur
Combine ingredients in a cocktail shaker with ice. Shake hard for only a few seconds. You can add two lime wedges to the shaker or add a lime slice to garnish at the end. Strain into a cocktail glass and serve. Unless you're doing multiple Cosmopolitans at a time I suggest replacing the ice after every one; that way the melted ice doesn't damage the flavor of the drink.
