After reading this thread, I'm going to order some of the Anson Mills rice, which I've never had before.
Their polenta is my very favorite on the planet, though, and I can't recommend it enough. The other corn products have a justly-earned rep, but I personally think there are a lot of good cornmeals out there, if we're talking basic cornbread opportunities.
That said -- I hate how at Anson Mills you have to either buy a tiny pouch of an item or 10 pounds. I don't get why this works for mail order. By "works" I mean works for the retail consumer. Sigh.
