3 fresh mint leaves
1 tablespoon mint simple syrup (recipe below)
1 fresh mint sprig
A short straw like this pretty metal one
To make the mint simple syrup, bring one cup of sugar and one cup of water to a boil in a medium saucepan. Once the mixture boils, stir for five minutes or so until all the sugar has dissolved. Remove the mixture from the stove and add 10 to 12 fresh mint sprigs. Let the syrup cool completely. Pour it into a glass jar, cover it, and put it in the refrigerator for 24 hours. Remove the syrup and discard the mint.
Now place the fresh mint leaves and mint simple syrup in a chilled julep cup like this one. Gently press the leaves against the cup with the back of a spoon to release its flavors. Pack the cup tightly with crushed ice. Pour bourbon over ice, and serve immediately with a pretty straw.
