Mike Perez set out to put a smash on the menu and landed on something that, in his words, just screams summertime: shiso, peach, and rye. Buster Sword muddles lemon into a base of Old Overholt, Rinquinquin peach aperitif, and shiso liqueur, then hides the whole beautiful mess inside a julep tin packed with pebble ice. It drinks bright, herbaceous, and refreshing—and, like any good julep, it's stronger than it lets on.
