Walk up to most bars and order a julep, and you'll find yourself facing a glass of bourbon, muddled mint, and powdered sugar: the classic mint julep. But to the cocktail purist, "julep" doesn't mean mint. It's a type of drink, one in which any spirit (not just bourbon) is mixed with any herb or spice (not just mint) and any sweetening element (not just sugar). With that definition in mind, we decided to start riffing. Of course, there's a reason the mint julep is the most famous version of the drink — it's a beautifully balanced beverage — so we took it as our starting point.
