In this video, you'll see how to mix the original mint juleps. You'll see how to make simple syrup with mint leaves, which is the key to the cocktail's slightly sweet, minty flavor. Mound crushed ice in a glass (or better yet, in a frozen silver goblet) and pour in bourbon and simple syrup. So easy! It's the official cocktail of the Kentucky Derby. But it's delicious and so refreshing whenever fresh mint is in season.
