First, take your martini glass and wet it with water. Place martini glass in the freezer so it will be chilled by the time you are ready to pour your martini.
Add six raspberries and the leaves from one spring of rosemary to a cocktail shaker. Next, add the Cointreau to the cocktail shaker and muddle the raspberries and rosemary leaves until the raspberries are smashed.
Next, add raspberry vodka, fresh squeezed lime juice, and cranberry juice to the cocktail shaker.
Lastly, add a handful of ice to the cocktail shaker. Add the lid to the cocktail shaker and shake for 20 seconds.
Remove the chilled glass from the freezer and pour cosmo into the glass.
