For the strawberry orange punch, wash and quarter the strawberries. Pour Cointreau over them and refrigerate for about 2 hours.
Freshly squeeze the orange juice and add to the marinated strawberries along with the Prosecco. Chill the punch again for at least 2 hours before serving.
Preparation Tip:
If you prefer to enjoy the strawberry-orange punch a little lighter, dilute it as desired with sparkling mineral water.
