Select and pre-chill a Nick & Nora glass.

Prepare an orange zest twist for garnish.

Stir the Cuban rum, cream sherry, and aromatic bitters with ice. If desired, add drops of saline solution for a touch of complexity.

Strain the mixture into the chilled glass.

Express the orange zest twist over the cocktail to release its oils, then use it as a garnish.
