Ahh, the Mint Julep. It is the drink of the Kentucky Derby and one of the best known bourbon cocktails made to date. Like the Old-fashioned, this drink requires muddling, but in this case you are muddling mint and simple syrup. Once the essence of the mint has been release, fill the glass with crushed ice and add your bourbon. It is simple but delightful and can lead you to a variety of other "stick" drinks.
