OH MY GOSH what's the secret to getting pita to puff correctly?

Toast

Holy hell! I thought I had perfected pita making during the winter. Now that it's summer, it seems much harder to get it to puff. It's driving me nuts! I dont know what to do!

Break off a piece of dough, shape into a ball and let it rest and rise and then roll it out flat without reshaping the ball, just flatten it.  Let it rise a little bit then bake.  The skin will act like a balloon and the trapped gasses inside will make it expand and puff up.  Has nothing to do with Hell or being Holy.  But I suppose a good deep breath first is almost as good as a prayer.

In winter the air is often much dryer making it easy to form a skin around a dough ball.  If your humidity is high, try powdering the outside of the individual dough balls with more flour after shaping them.
