Caroline Block, who also works at Marvin, with Pierangeli's "Moonshake Sour," made with 1 oz. Old Overholt rye whiskey, 1 oz. Laird's Applejack Brandy, 3/4 oz. fresh lemon, 1/2 oz. simple syrup (1:1 ratio of water to sugar), and two dashes of Fee Brothers Old Fashioned Bitters. Shake, double strain into a chilled rocks glass, and garnish with a flag (a brandied cherry and an orange slice).
