Preparation

Make the mint syrup:

• In a small saucepan, stir the mint with the sugar and 3/4 cup water, crushing the mint lightly with the spoon. Bring to a boil over medium-high heat and boil for 1 minute. Remove from the heat and let cool in the pan, about 30 minutes. Strain into a small container. Use immediately to make the cocktails or chill for up to 2 weeks.

For each cocktail:

• Have a chilled 8- to 10-oz. cocktail or wine glass ready. In a cocktail shaker, combine 1 Tbs. of the mint syrup with 1 cup ice, 1/4 cup bourbon, and a lemon slice. Shake for 30 seconds; pour into the chilled glass. Garnish with a mint sprig.
