The Champagne Etoile
First, you’ll make the syrup. Combine the sugar, water, bean and seeds in small pot. Bring to a boil over medium heat and cook until the sugar is dissolved. Let cool to room temperature and discard the bean.
For one cocktail, add a shot of bourbon and two tablespoons vanilla bean syrup to a chilled champagne flute. Fill to the top with prosecco. Squeeze lemon juice into glass and drop rind in. Serve.
