The French Laundry has developed a gluten-free flour so well-designed that it can substitute cup-for-cup with regular AP flour.  As in, put away your 6 different kinds of millet, buckwheat, garbanzo, etc. flours and your potato starch and guar gum measured out to hopefully blend to a successful consistency, and just use Keller’s C4C.  Is this too good to be true? I know I’ll be stopping by Williams Sonoma this week to pick up a bag to give it a test drive in my Brooklyn kitchen.  Has anyone tried C4C yet?
