Sir Isaac Newton Cocktail

Preparation

Combine the syrup, lemon juice, brandy, and bitters in a cocktail shaker with ice. Shake vigorously, then strain into a chilled cocktail glass. Float the apple slice on the drink for a garnish, and serve.

*To make the apple cider-cinnamon syrup, bring 4 cups of good-quality apple cider to a boil over medium heat. Reduce the heat to medium-low, add a cinnamon stick, and continue to cook, stirring occasionally, for about 25 minutes, or until the cider has reduced to the consistency of syrup. Bring to room temperature, then refrigerate in a tightly covered container. The yield is about 4 ounces.
