Jabejak, I've checked out the pizza dough recipe in the EDC book. The recipe is Ok but the process is not good. Any bread type dough needs WARM fluid to activate if it is to double in the 30 mins. You can double the dough using cold water or even in the fridge but it will take 8/ 12 hours, even in a warm climate. Try it again using warm fluid. Make sure that you keep the dry yeast packet firmly closed. The ideal room temp is between 20 and 25 degrees.
