Place the fresh mint leaves and sugar into a sturdy muddler. Gently press and twist the leaves until fragrant and slightly bruised, releasing the mint oils and producing a light green mash.
10 leaves fresh mint leaves, 2 teaspoons granulated sugar
Add the bourbon to the muddled mint and sugar mixture. Stir with a bar spoon for about 10 seconds to combine and dissolve the sugar further, ensuring the mint flavor infuses the alcohol.
2 oz bourbon
Fill a cocktail glass with crushed ice, leaving some space at the top. Use an ice crusher or blender to produce fine, snow-like crushed ice if not already prepared.
1 cup crushed ice
Pour the bourbon and mint mixture over the crushed ice. Gently stir with a bar spoon to chill and combine the ingredients, creating a slushy, icy consistency.
