I used the King Arthur "clone" of 00 yesterday. I picked it up on a lark at a chef supply store. The bag is pictured above. It worked alright, but not nearly as the Caputo 00 I've been using the last few months. I'm not an expert, so I've got no place to be critical of any miller. I'll just attest to my opinion that I think I need more protein than what's in this blend. I didn't realize it's protein level until I read this post today.
