Demerara rum, lime, mint, and dual bitters — the most beautiful bitters presentation in cocktail making.
The Queen's Park Swizzle was created at the Queen's Park Hotel in Port of Spain, Trinidad around 1920. The swizzle stick — a branch from the Quararibea turbinata tree, which grows naturally with perpendicular branches that act as whisks — originates in the Caribbean, where it was used to mix rum drinks long before the cocktail shaker existed.
The dual-bitters presentation is the drink's defining visual: Angostura (dark red, made in Trinidad) on one side and Peychaud's (bright pink, made in New Orleans) on the other. They bleed through the crushed ice in opposite colours. The Angostura comes from the same island as the cocktail — using Trinidad's own bitters to garnish Trinidad's own cocktail is a nice symmetry.
Add ½ oz falernum and ½ oz Velvet Falernum to the base. Replace Demerara with a Jamaican dark rum. More tropical and layered.
Split the rum between 1 oz Demerara and 1 oz Jamaican dark rum. Add ½ oz grenadine alongside the simple syrup. Sweeter and more tropical.
Add 3 thin cucumber slices to the muddle alongside the mint. The cucumber freshness cuts through the rum's richness beautifully.
