I picked up a bushel each of wheat and rye for $26 at the nearby feedmill. We have to watch out for stray corn kernels or protein pellets, but the price is unbeatable. We'll do a coarse grind in our Victorio food mill, then sift it in a fine mesh strainer. The result is a somewhat fine whole wheat "white" flour, and plenty of bran to use in flatbread (like Swedish knackerbrod) or as breadcrumbs
