Spiced Maple Bourbon Fizz

1. To make the spiced maple syrup. In a medium pot, bring 1/2 cup water, the maple, cinnamon, cardamom, star anise, and ginger to a boil over high heat. Boil 2-3 minutes, then remove from the heat. Stir in the orange zest. Let cool, then strain the syrup into a glass jar. This syrup makes enough for about 6 drinks.
2. In a cocktail shaker, combine 1-2 tablespoons maple syrup, the bourbon, lemon juice, and orange bitters. Add ice and shake. Strain into a glass. Top off with champagne. Garnish with an orange slice and star anise, if desired.
