2 oz. bourbon 1 oz. boiled cider or cider syrup (see note) A strip of lemon zest
Combine bourbon and cider syrup over ice and stir gently. Twist lemon zest and drop into drink, stir again, and serve.
Note: Boiled cider is a substitute to maple syrup that's found throughout Vermont, New Hampshire, and Massachusetts. To make it at home, gently boil a gallon of apple cider in a heavy-bottomed pot, stirring occasionally, until it has reduced to ⅛ (making 2 cups syrup), about 2 hours. Let cool to room temperature and store, refrigerated, in an air-tight container.
