Native to Southeast Asia, the flower has been used for centuries in traditional teas and cuisine. Western bartenders and mocktail enthusiasts recently adopted it for its natural deep blue pigment and its pH-sensitive characteristic, leading to the creation of theatrical, color-changing drinks like this one.
