Triple sec has been a staple of the back bar for well over a century, tracing its roots back to nineteenth-century France. The name translates roughly to 'triple dry,' referring to the traditional distillation and flavor profile of the orange peels used in its creation.
Unlike heavier curaçaos, triple sec was developed to offer a cleaner, crisper, and more intensely bright citrus flavor profile. This made it an instant favorite among pioneering bartenders who were just beginning to experiment with complex mixed drinks.
Today, it remains an indispensable ingredient in dozens of classic recipes, from the Cosmopolitan to the Sidecar, proving that good citrus never goes out of style.
