Southern Mint Julep

4 cups sugar
2 cups water
1 ounce (1 bunch) mint leaves, plus another additional bunch, for serving
Kentucky bourbon, such as Maker's Mark
Crushed ice

Stir sugar and water in a heavy medium saucepan over medium heat until sugar dissolves. Bring to a boil. Reduce heat to simmer gently for 10 minutes. Place 1 ounce fresh mint leaves into large bowl; pour hot syrup over leaves. Let cool to room temperature, then cover and refrigerate overnight.

Using a slotted spoon, remove mint leaves from syrup and discard mint. Pour mint syrup into large pitcher. Cover and refrigerate until ready to serve.

Set out pitcher of mint syrup, bourbon, and crushed ice. Arrange additional mint sprigs in a bud vase with water to keep them fresh. Allow guests to assemble their own cocktails, adjusting measurements to suit their own preferences.

In general, fill glasses with crushed ice and add approximately 1/4 cup bourbon and 2 tablespoons mint syrup, then add as many mint leaves as desired and stir to combine. Garnish with a sprig of mint and enjoy.
