- 8 to 10 mint leaves, plus 1 mint sprig, for garnish
- 1 teaspoon sugar
- 2 1/2 ounces bourbon
- Sparkling water
- Crushed ice
- Twist of lemon peel, for garnish
- Confectioners' sugar, for dusting
Chill a (tall) Collins glass in the freezer for 10 minutes.
Combine the mint leaves, sugar, 1 ounce of the bourbon and a splash of sparkling water in the chilled glass. Use a spoon or wooden muddler to gently crush (muddle) the mint into the mixture.
Add a handful of crushed ice and stir vigorously. Add the remaining 1 1/2 ounces of bourbon and a splash of sparkling water. Fill the glass to the brim with ice (tightly packed), then use a bar spoon or knife to agitate the mixture ("with relish" according to Jim Hewes) until frost appears on the outside of the glass. Garnish with the mint sprig and lemon twist, and dust the top with confectioners' sugar. Insert a straw and serve immediately.
