Lively but light, this sparkling citrus punch is an excellent choice for a New Year's Eve party that lasts well into the night. Simple syrup infused with bay leaf lends herbaceous flavor, while fresh grapefruit juice and clear cranberry juice create the blush-toned hue for this vodka, Cointreau, and prosecco based drink. Sunny sliced kumquats added at the end make for a seasonal garnish that partygoers will want to toast to.
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.
