Optimist Old Fashioned

Select and pre-chill an Old Fashioned glass.

Prepare an orange zest twist as garnish.

Stir the bourbon whiskey, Bénédictine D.O.M. liqueur, orange bitters, and chocolate bitters with ice.

Strain the mixture into the ice-filled glass, ideally over a large cube or chunk of block ice.

Express the orange zest twist over the cocktail and use it as a garnish.
