Gimlet

Gin and lime in a Royal Navy-rooted cocktail — tart and sweet with Rose's Lime Cordial, or clean and dry with fresh juice as craft bartenders now prefer.

The Gimlet's documented origins lie in the British Royal Navy's requirement that sailors consume citrus juice to prevent scurvy — the vitamin C deficiency disease that had been recognized as a major cause of sailor death on long voyages since at least the 18th century. Lauchlan Rose, a Scottish merchant, patented a process for preserving lime juice with sugar syrup without fermentation in 1867, creating Rose's Lime Cordial — the concentrated lime product that became the standard shipboard citrus preparation and the ingredient most associated with the classic Gimlet. The cordial's sugar content and lack of fermentation gave it an indefinite shelf life, solving the practical problem of fresh citrus's spoilage at sea. Gin's dominance in the British military and merchant marine — a product of the Royal Navy's historical preference for the spirit — made it the natural pairing. The Gimlet was likely consumed in various forms aboard ships and in colonial naval stations before it entered civilian bar culture in the early 20th century. Raymond Chandler immortalized a specific preparation in his 1953 novel The Long Goodbye, in which his detective Philip Marlowe and the character Terry Lennox discuss the ideal Gimlet: half gin and half Rose's lime juice, nothing else — a formula whose sweetness from the cordial produces a drink distinctly different from the fresh-lime version that craft cocktail bars prefer.
