Soufriere Negroni

Select and pre-chill an Old Fashioned glass.

Prepare an orange zest twist for garnish.

Stir the spiced rum, Strucchi Red Bitter, and Difford's Falernum liqueur with ice until well chilled.

Strain the mixture into the prepared glass, filled with ice, preferably using a large cube or a chunk of block ice.

Express the orange zest twist over the cocktail and place it in the drink as a garnish.
