Fill the champagne flute with ice to chill while you prepare the drink.
Let it sit for 2-3 minutes.
Empty the ice from the flute.
Pour the orange juice, cranberry juice, and simple syrup into the flute.
Stir gently with a bar spoon to mix the juices.
Top slowly with prosecco or champagne.
Garnish with an orange twist.
Notes
Serve the drink right away to keep the bubbles fresh and lively.Keep all ingredients cold before mixing for the best results.For a less sweet version, use less simple syrup or skip it.The recipe makes one serving but you can double or triple it for groups.
