Anyone have an idea where this flour can be found? I am looking to make some pizza dough from scratch and this flour simply isn't available in the Denver area. Everything is gluten-free. I have found King Arthur's at Whole Foods, but of course they don't have the High-Gluten flour. They have unbleached Bread flour by King Arthur-not sure if this will work. I have seen Red Mill Vital Gluten Wheat flour. Not worth it to order online. Any stores carry such an animal in Denver, or is there a close substitute? Thanks for any suggestions.
