(Before I begin may I ask you to pardon the flour mess?:) You should 've seen the floor!;)
I posted before about Puff-less Pitas and stiff doughs.
But I have another suggestion if you are still having trouble getting your pita bread to puff up like a Puffer Fish!
It you look at the two unbaked pita above, do you notice anything?
The one on the left is puffy and soft.
The one on the right is wrinkly and deflated some.
If I stick them in the oven, just like this, the one on the right probably won't puff.
What did I do to cause this?
I moved them!
I let them rise on the counter and tried to lift them without de-puffing to this rack. It worked with one but not the other.
So my tip?
Try to let them rise on whatever you are going to bake them on. Moving them can knock the puffy rise right out of them! They can't help it- they're just sorta sensitive that way ;-)
Hope that helps get you closer to a Puffy Pita!
(If they fail- you can often slice them open with a sharp knife or kitchen scissors.)
I love Tammy's Whole Wheat Pita Recipe!
