two day ago I had the possibility to visit a Lavash bakery near Yerevan. Lavash is the soft Armenian bread, popular in most of the Caucasian nations, whose origin date back to old time . It is made essentially with flour, water and salt. The typical flat shape is due to the traditional processing: the dough is rolled and fixed on a special stuff that is used to press the bread against the hot walls of a clay oven. Thanks to the thinness of the dough and to the hot temperature of the oven, the cooking time is reduce to few second (5-15).
