Muddle mint leaf and simple syrup in a chilled rocks glass. Fill with crushed ice. Add bourbon.
The Mint Julep, originally made with bourbon, was detailed in the first definitive guide to cocktails, “Bartender’s Guide: How To Mix Drinks.” The guide was published in 1862 by Jerry Thomas, who was considered the father of American mixology. This drink was also reportedly a favorite of William Faulkner’s. This is all to say that we know the Mint Julep was one of the originals. We’ve paired ours with a bowler hat and a fob watch; very 1800s dapper indeed.
