About Black Glutinous Rice
Black glutinous rice (pulut hitam) is dessert rice: soaked overnight, then simmered long into a porridge sweetened with palm sugar and finished with coconut milk — Indonesian bubur ketan hitam, Thai black rice pudding. It differs from regular black rice in starch (glutinous) and use (sweet), and it needs the overnight soak desperately. The 1:3 ratio makes pudding, not side-dish grains.
