Mint julep is a mixed alcoholic drink, or cocktail, consisting primarily of bourbon, sugar, water, crushed or shaved ice, and fresh mint. The term "julep" is generally defined as a sweet drink, particularly one used as a vehicle for medicine. The Mint Julep gained prominence in the southern United States during the 18th century, and it first appeared in print in 1803.
In a highball glass, lightly muddle the mint leaves in the simple syrup.
Add the bourbon then pack the glass tightly with crushed ice.
Stir until the cup is frosted on the outside.
Garnish with a mint sprig.
