Keyser Söze

Use 2:1 rich simple syrup for its listed portion.

Select and pre-chill a cocktail coupe.

Prepare an orange zest twist for garnish.

Shake the cognac, Hayman's London Dry Gin, gentian liqueur, freshly squeezed lemon juice, and rich sugar syrup with ice until well chilled.

Strain the mixture into the pre-chilled coupe.

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