“The fire caramelizes the sugar, giving the drink depth and added richness,” says Lauren Schell of Seaworthy in New Orleans. “It's a crucial element of balance, in addition to being eye-catching and purposefully interactive.” The Chartreuse-meets-sugar fire inside a hollowed-out lime might be simple to create but is a visual stunner while simultaneously helping to balance out the drink’s citrus notes.
Add all of the ingredients except for the Chartreuse, bitters and sugar cube into a shaker, and dry-shake.
Pour into a chilled rock glass, top with crushed ice, and float 3 dashes of Angostura bitters.
Hollow out a lime half, and place it cut side up on top of the drink. Add the Chartreuse and sugar cube to the lime half. Light the lime half, aiming for the Chartreuse, let it burn for 10 to 15 seconds, and blow out the flame.
