We tried the cup 4 cup pizza crust mix tonight and it was by far the best gluten free crust we have done. Most of the others have been gritty and tough to get crispy... This one cooked and tasted just like the non GF alternatives.
Swmbo is celiac and we had all but given up on egg pizza when we came across thus suggestion.
We tried this based on a suggestion in the baking forum, but Swmbo isn't much on beer so I stuck close to the package directions except cooking on the egg. I got the egg to a stable 500 with the stone, par cooked in a pan for 10 minutes then removed the pan and added toppings cooking right on the stone for another 10...
The manufacture website had a store locator so we found the mix at Williams Sonoma, but we also noted that it's available on Amazon. http://www.amazon.com/Gluten-Free-Pizza-Crust-17-9/dp/B00H8ZRX14/ref=sr_1_1?ie=UTF8&qid=1444529406&sr=8-1&keywords=Cup+4+cup+pizza
Needless to say it was a home run.
