Make a syrup of water, sugar and chopped mint leaves in a small pot; boil on high until the sugar is dissolved. Let syrup cool then strain liquid to remove mint leaves. Fill two glasses or goblets with crushed ice and pour 4 ounces of bourbon and half of the mint syrup into each glass. Garnish with a sprig of fresh mint.

Makes two drinks. (Recipe can be easily doubled, tripled, and so on, depending on how many drinks you want to make.)
