Okay, I'm going to be using this a lot. This is Silvana Nardone's all purpose flour from Cooking for Isaiah. I'm giving her all the credit, because it is her blend...but a lot of my recipes are probably going to be using this blend, so I thought I'd pass it on, with my minor change--I use brown rice flour instead of white rice flour.
By they way, you really should buy "Cooking for Isaiah" if you haven't yet. Or ask for it for Christmas. ;)
Update 1/25/12: I've decided not to have her recipe posted here. It's her recipe, so I feel it isn't fair to her for people to be coming to my site for her work. You can find her recipe on page 15 of her book, Cooking for Isaiah, which is part of the preview on Amazon. So, go to Amazon, check out the flour recipe--and buy her book, it's a good book. And, go here to check out my flour blend, it works really well, I really love it and use it now instead of Silvana's (her's is really good, too, though).
