Made a GF Deep Dish using a gf flour blend and the cast iron skillet technique..
http://www.pizzamaking.com/forum/index.php/topic,2047.msg18031.html#msg18031Dough: (sorry no baker's %)
1 cup white rice flour
1/4 cup tapioca starch
1/4 cup corn starch
1/4 cup potato flour
1/4 cup corn meal
1/2 tsp xantham gum
1/2 tsp salt
1/2 tsp IDY
1/2 cup water
3 tbs olive oil
Mixed dry ingredients, blended in liquids. Balled and let rise at RT for ~6 hrs. It smelled yeasty but didn't really rise too much. Poured some olive oil in a 10.5" cast iron skillet and pressed out dough to go an inch or so up the sides. Put down ~8oz sliced low moisture mozz, 8oz spicy italian sausage (raw), 2 cloves chopped garlic, oregano, then I added a box of strained Pomi tomatoes, that I further strained in a sieve, topped with more oregano.
Put in cold oven, cranked it to 500. Once it got to 500 lowered to 400 and baked for 30 minutes. I've previously followed the original link using the gluten recipe and really liked the results. The GF version turned out pretty good, but barely any oven spring in the dough. Wondering if I proofed the dough shaped in the skillet if that would help. Also maybe par-bake the crust next time. I would push the dough's lip down to stay even with the sauce, as the above sauce dough got too crunchy baked in this way. Overall very good and I would make again. My girl is GF and she really liked it.
