Ingredients

• 3 oz. whisky
• 1.5 oz. simple syrup
• 1/4 lemon (or tablespoon of lemon juice)
• 2-3 dashes of bitters
• 5 mint leaves

Preparation

Using a muddler or the handle of a wooden spoon, mash mint leaves, lemon half, and Simple Syrup in a 16-oz. mixing glass or a cocktail shaker 4–5 times just to release juices and oils. Add bourbon. Transfer to an Old Fashioned glass. Fill halfway with crushed ice, stir, then mound more crushed ice on top. Garnish with mint sprigs.
