Lime Rickey is any of several mixed drinks, some alcoholic cocktails and some not, that feature lime juice as a key ingredient. Other components may include, gin, rum, vodka, bitters, and carbonated water, and possibly simple syrup or other flavorings. Soda-fountain versions may include grape, cherry or raspberry syrup, which makes it essentially a limeade. The Utah based Arctic Circle Restaurants have such a variation called Lime Ricky, which has no alcohol, and a unique lime flavor and grape syrup along with crushed ice. A popular Cuban version is the mojito, made with key lime juice, rum, simple syrup, soda water and muddled mint leaves. The Lime Rickey is also known as a Gin Rickey.
