orange slice or 2-inch orange peel, for garnish
ice
vodka
cranberry juice cocktail
triple sec, such as Cointreau or Grand Marnier
freshly squeezed lime juice (from about 1 lime)
If using a garnish, cut a 1/4-inch thick slice of orange. Cut a slit from the center of the orange to the side. Alternately, use a vegetable peeler to peel a 2-inch strip of peel from an orange.
Fill a cocktail shaker with 1 cup ice, 1 1/2 ounces vodka, 1 1/2 ounce cranberry juice cocktail, 1 ounce triple sec, and 1 ounce freshly squeezed lime juice. Seal the shaker and shake vigorously until the outside of the shaker is frosty, about 20 seconds.
