Perfect Homemade Pita Bread

The flavor of this pita is perfect, the dough was easy to work with, BUT I could not get mine to puff/form a pocket. Followed the directions exactly but after not much luck (1 puffed) I used reviewers suggestions of cooking in cast iron stove top (none puffed). So what can I glean from this one successful pita - it was smaller than the others, not thinner (in fact maybe a bit thicker) and the oven needs to be really hot. I will make these again with that in mind - smaller pitas with slightly more heft (closer to 1/4 inch thick).
