This festive cocktail gets its coral color from mixing regular orange, blood-orange, and pink-grapefruit juice together.
Place 2 martini glasses in the freezer for at least 10 minutes. Fill a cocktail shaker halfway with ice. Add vodka, Cointreau, and citrus juices. Cover; shake vigorously for 30 seconds. Strain the liquid immediately into chilled glasses, and garnish with strips of blood-orange zest.
