Have you ever tried it? I never heard of it until today on the noon news.

From Wiki:
Black rice (also known as purple rice or forbidden rice) is a kind of sticky rice which is one of several black colored heirloom plants producing rice variants such as Indonesian black rice and Thai jasmine black rice. Black rice is high in nutritional value and contains 18 amino acids, iron[citation needed], zinc, copper, carotene, and several important vitamins. The grain has a similar amount of fiber to brown rice[1][unreliable source?] and like brown rice, has a mild, nutty taste. In China, black rice is claimed to be good for the kidney, stomach and liver[citation needed]; these claims have not been independently verified or established.

It is a deep black color and turns deep purple when cooked. Its dark purple color is primarily due to its anthocyanin content, which is higher by weight than that of other colored grains but more limited in the number of different anthocyanin species present.[2][3] It is suitable for making porridge and it can also be used for making dessert, traditional Chinese black rice cake or bread.
