Pink Grapefruit-White Cranberry Sparkling Punch
In a small saucepan, bring sugar, grapefruit zest, bay leaves, and 1/2 cup water to a boil, stirring until sugar has dissolved. Let cool completely, about 1 hour. Strain, discarding solids, and refrigerate in an airtight container until cold, at least 1 hour and up to 1 week.Advertisement
In a punch bowl or large pitcher, stir together syrup, grapefruit juice, vodka, Cointreau, and cranberry juice. If not serving right away, cover and refrigerate up to 1 day.
Add ice, top with prosecco and club soda, and garnish with bay leaves and kumquats. Serve immediately.
To keep this cold longer, store the vodka and Cointreau in the freezer (their high alcohol percentage will prevent freezing), and prechill your bowl in the refrigerator. Use large ice cubes, which melt slowly, so the punch won't get diluted as quickly.
