The key here is making the simple syrup in advance and using special short silver julep cups.
Yield: Makes 12 drinks
1 cup sugar
2 bunches fresh mint
1 (750-milliliter) bottle bourbon
3 cups (24 ounces) chilled club soda, optional
First, make the sugar syrup (simple syrup). Mix the sugar with 1 cup water in a small saucepan, bring to a simmer, and cook just until the sugar dissolves. Pour into a container, add 1 bunch of the mint, cover, and refrigerate overnight. Remove the mint, draining it well, and discard it.
For each julep, fill a metal julep cup (or an old-fashioned glass) with crushed ice. Pour in 1 tablespoon of the mint syrup and 2 ounces (¼ cup) bourbon. Stir. Add a splash of club soda, if desired, garnish with fresh mint, and serve.
As a timesaver, keep a container of simple syrup in the refrigerator to have on hand for cocktails and for sweetening iced tea.
