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

Chill a cocktail coupe glass in advance to ensure a crisp, refreshing serve.

Prepare an orange zest twist for garnish, setting it aside for later use.

Combine Hayman's London Dry Gin, Calvados or your preferred apple brandy, Bols Blue Curaçao, Strucchi Dry Vermouth, freshly squeezed lemon juice, and rich sugar syrup in a cocktail shaker.

Add ice to the shaker and shake vigorously until well-chilled.

Fine strain the mixture into your pre-chilled coupe glass to achieve a silky texture.

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