This wonderful drink was created by my good friend (and now wife) Audrey Saunders, proprietor of the Pegu Club in New York City. You will notice that it is closely related to the Mojito, but with far more elegance and sophistication. Audrey garnishes her original version with a sugar-coated vanilla bean as shown her in this recipe. If you don't happen to have any handy, feel free to make it without, but you do owe it to yourself to try it one day with that little added extra touch.
Garnish: Sugar-coated vanilla bean
Muddle lime juice, syrup, mint in a mixing glass. Add rum, bitters, ice, and shake well. Strain into cocktail glass, and top with champagne.
