There are a couple of great books out there about rice in all its mysterious variety.  We have and have used Seductions of Rice by Jeffrey Alford and Naomi Duguid (2003) – it is exhaustive to say the least, and a great addition to any cookbook collection. Alford and Duguid travel the world for their food research, and they take gorgeous photographs as well.  I don’t think they missed a grain of rice in their studies.  Another, which I have not seen, is The Rice Book by Sri Owen.  Written in 1993 it has a lot of great reviews and has gone on my Amazon wish list.
