A sophisticated twist on the classic Old Fashioned, the Bitter Old Fashioned incorporates aromatic bitters to enhance the depth of flavor, creating a rich and complex cocktail.
In an Old Fashioned glass, place the sugar cube and add the Angostura and orange bitters. Muddle together until the sugar is dissolved.
Pour in the bourbon or rye whiskey over the muddled sugar and bitters mixture.
Add a large ice cube or several smaller ones to the glass. Stir gently to combine and chill the drink.
Express the oils from an orange peel over the drink by holding it over the glass and giving it a twist. Then, drop the peel into the glass as a garnish.
Notes
For a less sweet version, reduce the amount of sugar or use a sugar substitute. Experiment with different types of bitters to find your preferred flavor profile.
