Everyone?s favourite indulgent ice cream brand, Magnum, has launched the world?s first pairing of ruby chocolate and ice cream. The brand has dipped white chocolate ice cream with a raspberry swirl into ruby chocolate to create Magnum Ruby, the new addition to its range. The world?s fourth type of chocolate (after dark, milk and white), ruby chocolate was created by high-quality chocolate producer, Barry Callebaut, after a decade of development.
