The rice's vivid blue color comes entirely from steeping butterfly pea flowers — the same natural pigment found in some blueberries — with no artificial dye in the traditional recipe.
Rice is steamed with butterfly pea flower petals until it turns deep blue, then piled with a tangle of raw herbs and shredded vegetables, a stuffed chilli, salted egg, fried fish, and crackers, all mixed together before eating. Kelantan market stalls and night bazaars sell it as a colorful, herb-heavy daily rice plate.
