This is the one we have fenagled over a few experiments. We have a gluten free friend and have developed some fun and delicious stuff.
1c white rice flour
1c brown rice flour
1c tapioca flour
Pinch or 2 of xanthine gum
Pinch salt
Pinch baking powder
3 Tbsp sugar, divided
1 Tbsp active yeast
1 1/4 cup warm water, divided
Dollop olive oil
Put the yeast in 3/4c or so warm water and after a few minutes put half the sugar in it. Mix the dry, then add the wet and mix it together with a wooden spoon, but don't beat the hell out of it. Glob it on your stone (preferred. Sheet will work too but grease it a bit) and with your fingers work it out toward the edges until it is even and quite thin. It should look like a big golf ball with all your finger dimples. Pre cook the crust for 20-25 mins on 350f with fan. It'll look dry and maybe a bit cracked, but it's all good. Take it out, sauce it up, and top it as you will, captain. Back in until she's golden and bubbly.
