Notes
Instead of serving this cocktail over ice, put all of the ingredients into a cocktail shaker, shake for 15 seconds, or until chilled, and then strain into a glass to serve.
To make a party sized batch (8 servings), mix 2 cups vodka, 3 cups cranberry juice, and 3 cups pineapple juice in a large pitcher. This mixture will keep for several days in the refrigerator.
