2 oz bourbon (I like Maker’s Mark)
3-4 tablespoons superfine sugar (see note)
Generous handful of fresh spearmint
Into a silver julep cup, mason jar, or highball glass, press 2 tablespoons of sugar with a small amount of water to create a paste. Add a layer of fresh mint leaves and crush gently. Top it with a layer of crushed ice. Sprinkle sugar and another layer of mint leaves, then top with another layer of crushed ice. Continue until the glass is full, then pour in bourbon.
Note: Superfine sugar dissolves quickly, but regular sugar is fine too. Don’t use powdered sugar—it contains cornstarch and can gum up a drink.
