Bread-Bakers v105.n005.10

Hi -- My family enjoys pita bread, and we were wondering what causes it to 
form its characteristic pocket.  Any explanations would be much 
appreciated.   I'd love to try to bake some pita, especially if I can make 
the dough in my bread maker.  If you have an easy recipe, please share it 
with us.  Thanks and have a great weekend --   Meryl
