Note : Paper thin mountain bread has been around for thousands of years traditionally from areas near the Lebanese and Syrian border. The art of making mountain bread is passed down by women from one generation to the other. The bread is made from a variety of grain flour plus wheat flour, salt and water. Mountain bread is not suitable for people suffering from coeliac disease.
