Muddle mint leaves at bottom of a Footed Rocks or Rocks glass and fill with crushed ice. Pour lime, honey, and Mezcal over the ice and churn with a spoon. Add more crushed ice & slowly pour bitters over top. Garnish with 1/4 ounce of Combo Bitters (2 parts Angostura and 1 part Peychaud) and a mint sprig.
