Glutinous rice
Glutinous rice can be used either milled or unmilled (that is, with the bran removed or not removed). Milled glutinous rice is white and fully opaque (unlike non-glutinous rice varieties, which are somewhat translucent when raw), whereas the bran can give unmilled glutinous rice a purple or black color. Black and purple glutinous rice are distinct strains from white glutinous rice. In developing Asia, there is little regulation, and some governments have issued advisories about toxic dyes being added to colour adulterated rice. Both black and white glutinous rice can be cooked as discrete grains, or ground into flour and cooked as a paste or gel.
