Brandy Milk Fizz

1 large egg white

2 ounces Park Cognac

¾ ounce lemon juice

½ ounce simple syrup

½ ounce Frangelico

1 ounce heavy cream

4 ounces soda water, divided

Garnish: grated hazelnut

From its infancy in seventeenth-century England to its place on the sideboards of elegant Southern homes, milk punch is the favored festive go-to of blue-blooded New Orleanians, especially during Carnival and the holidays. But LeBas’ formula—lightened up with soda and frothy egg whites—would be at home under a beach umbrella.
