Most recipes for the Gimlet call for Rose’s lime cordial, as opposed to fresh lime juice. While I tend to use fresh juices and generally believe fresh juice is always better than artificially sweetened cordial, the addition of Rose’s does make a fairly decent cocktail.
But, a staunch opponent of scurvy, my preferred recipe stubbornly uses fresh lime juice, making up for the lack of Rose’s sweetness with some simple syrup.
2 ounces gin
1/2 ounce fresh lime juice
1/2 ounce simple syrup
Shake with ice and strain into a cocktail glass. Garnish with a lime.
