Also known as purple rice, black rice is a group of several types of Oryza sativa or Asian rice. Some of the varieties of black rice include Indonesian black rice, Philippine heirloom balatinaw black rice, Philippine pirurutong black glutinous rice, Thai jasmine rice, and kalo dhaner chaal (black paddy rice) from Bangladesh.
In China, black rice is also known as forbidden rice because, in the past, it was banned to regular folk and eaten only by the Emperor as it improved its health and longevity. In general, black rice takes longer to cook and turns purple with cooking.
