The Umami Bomb cookie combines burnt white chocolate with miso for a mouthful of umami flavour. Caramelising Valrhona ivoire chocolate takes the milky-sweet white chocolate beyond its one dimensional sweetness, past its otherwise vanilla mien, and into a sexier personality reminiscent of salted caramel. Chunks of said caramelised white chocolate are paired with the tangy saltiness of miso for a savoury edge.
