Alexis' family introduced me to the camtini. I'm pretty sure it's named for her mother Camille (correct me if I'm wrong, Alexis.) It's a vodka based martini with pineapple juice, cranberry juice, and champagne and it is definitely my drink of choice at her house.
Fill a shaker with ice cubes, add 3oz vodka, 1oz pineapple juice, 1oz cranberry juice and shake well. Pour a splash of champagne into the bottom of a martini glass and pour the vodka/cran/pineapple mixer on top. Enjoy!
