We were watching that Diners, Drive-ins and Dives show last night and they were at a Bosnian restaurant in Texas. The chef was making several dishes that incorporated a flatbread somewhat like a pita only much thicker.
I've scoured the interwebs and was surprised at the lack of information on how to make these.
Maybe use a pita recipe and form the loaves about 1/2" thick?
LINK go down the page below the baked beans....
We have a lot of "foreigners" (for lack of a better name) that come in our Whole Foods store. They buy 25 pound bags of Barley flour and use it make a flat bread that they say is better than chapati....I wonder if this is close.
