When I lived in Ann Arbor, I was able to buy 25 pound bags of flour from the Zingerman's Bakehouse. The flour itself was a King Arthur product that just said "Special" on it.
Now in Northwest Indiana, I want to make a lot of bread for friends, but all I can find in bags larger than 5 lbs. is bleached and bromated flours. I've looked at Sam's Club and at Gordon Food Services here. They have plenty of big bags, but it's all bleached and bromated.
Any ideas about sources for great flour in bigger bags?
Also, does anyone know what the effects of pleaching and bromate are?
