Simple, tart, and effortlessly refreshing, the Cape Codder is the no-fuss cocktail named for its beachy Massachusetts roots. Made with just vodka and cranberry juice, often with a squeeze of lime, it’s the kind of drink you can build right in the glass without breaking a sweat. First popularized in the 1940s by Ocean Spray (yes, really), it’s the blueprint for a whole family of cranberry-based drinks—and the unofficial sponsor of summer vacations everywhere.
