Fig Leaf

Chill a cocktail coupe in advance.

Combine the sweet vermouth, light rum, freshly squeezed lime juice, and a dash of Angostura bitters in a cocktail shaker filled with ice.

Shake vigorously until well-chilled.

Strain the mixture into the chilled cocktail coupe.

Garnish with a twist of lime peel, expressing its oils over the drink before adding it to the glass.
