southern, that dough recipe definitely has too little water. kuan, I'm going to have to disagree with you on that. It's the underhydration.
jock, add me to your paintball team. So far, it's me and you against kuan and Ma Facon.
I didn't check jock's figures, but I agree that less than 50% hydration for a pizza dough is very underhydrated. That is the main source of your problems, southern. There could be other smaller factors in your gluten development, but that dough is way dry.
Montelago's is 56% hydration, a little better, but that's still dry to my preference, though there's another 8% in oil.
Southern, I would say definitely use a recipe with a wetter ratio of water to flour than the one you're using. If you have a kitchen scale, use a recipe that's by weight, the flour will weigh out more accurately for you also.
Southern, isn't it nice when it's the recipe's fault and not yours!
