Step 1

Place the cointreau and cranberry juice in a cocktail shaker with ice. Shake 15 seconds until cold. Strain the liquid into a champagne flute. (You can skip this step if the cranberry juice is well chilled.)

Step 2

Top off the glass with champagne (no need to measure). Garnish and serve. (Note: You can also make a large batch of cointreau and cranberry juice ahead if desired, then measure out 6 tablespoons per glass.)
