The Gin Gimlet cocktail is one of those classics that have been around forever, and with good reason. The original Gin Gimlet was 2-parts gin to 1-part Rose's lime juice. Rose's Lime Juice is lime juice that is preserved with sugar, making it not only sweet but also shelf-stable. This gave the Gin Gimlet a tart and sweet flavor beloved by so many of us and as well as a prominent place in cocktail history.
