I've recently started buying organic milk because it keeps so much longer. Great for me, since I never know how much I'll use. Wish I could claim a health-concious reason, but it's really all about the expiration date.
Now, I'd love to find a grocery store to buy organic buttermilk at, as well. I generally only buy it when I'm making corn bread, but then I end up pouring out fair amount of it.
I know grocery store stocks vary by individual store, of course, but does anyone know of a chain that you always see carrying it?
