lavash
Thin, soft wheat flatbread baked in large sheets that can be folded and rolled.
Lavash is a thin flatbread made from wheat flour, unleavened or only lightly leavened, baked in Iran, Armenia and across the Caucasus. Fresh, it is soft and pliable; left exposed to air, it dries quickly and turns brittle. It is sold in Turkish, Persian or Middle Eastern grocers and often in well-stocked supermarkets.
Substitute:
Thin Turkish yufka flatbread sold for dürüm wraps, or large wheat tortillas, come closest; tortillas are a little thicker and softer but behave similarly when rolled or crisped in a pan.
