Our recipe testers called the big-batch cocktail recipe in this video refreshing and just sweet enough to leave you wanting one more glass. It calls for quite a bit of lime juice, which can turn into a chore if you find yourself with a bunch of lackluster citrus. To ensure you get the most juice from each lime, be sure to select fruit that is tender. Let the base recipe chill completely before serving, and don't make it too far ahead or else the lime will start to lose its punch.
