Crushed ice
1/2 oz mint infused simple syrup (add mint leaves to simple syrup as it cools)
2 1/2 oz bourbon
2 dashes Angostura bitters
Add 10 mint leaves to the bottom of a glass. Add simple syrup and muddle gently. Add 1/2 glass of crushed ice and pour in bourbon and bitters. Mix gently and top with more crushed ice until mounded. Garnish with generous sprig of "clapped" mint.
