Preparation

• Slice the vanilla bean in half lengthwise, removing and discarding the seeds. Sprinkle the sugar over each half of the bean, pressing lightly to ensure adhesion. Set aside.

• Add the rum, syrup, lime juice, bitters and mint to a cocktail shaker filled with ice. Shake 17 seconds.

• Double strain through a fine-mesh strainer into a martini glass.

• Top with the Champagne or sparkling wine. Garnish with the mint sprig and sugar-coated vanilla bean.

* To make simple syrup, combine 1 cup sugar and 1 cup water in a medium saucepan. Bring to a boil, stirring, until the sugar is dissolved. Let cool before using.
