A friend of mine is originally from Ferghana, and he told me about a bread they used to eat there when he was a kid, called "Lipioshka". I understand it is a rather traditional Uzbek bread. It is a little like a large bialy in shape: a round disc, thick around the edges and very thin in the center. The center is stamped with a special tool (or simply pricked with a fork) to prevent rising. Traditionally, it is baked in a Tandr, an Uzbek oven not unlike a Tandoor.
I attempted to make it from a similar sounding recipe in Maggie Glezer's "A Blessing of Bread". I've written about it extensively here: http://foldingpain.blogspot.com/2008/02/lipioshka.html
However, I am interested to know if you had heard of it, or of similar breads. Do you have recipes you can share? This is a fascinating bread to me, and I am surprised at how little information I was able to find about it.
