6–7 fresh mint leaves
1 Tbsp. simple syrup
2 oz. bourbon
Glass: julep cup (or highball)
Garnish: mint sprig
Combine the mint leaves, syrup and bourbon in a glass. Using a barspoon, crush the mint to release its essence into the liquid. Fill the glass with crushed ice. Gently press the spoon into the ice, shaking it to incorporate the bourbon-syrup mixture. Garnish.
