The Knickerbocker is a bold, fruity rum cocktail from the 1800s that deserves way more love. A pre-Civil War classic, it combines gold rum, raspberry syrup (or fresh raspberries), orange curaçao, and lime juice, delivering a tart, juicy, and slightly funky flavor profile with Caribbean roots and New York attitude. It’s a little tiki, a little punchy, and totally refreshing—like a Victorian vacation in a glass.
