On a Monday morning this past May, on the way from Gyumri to Yerevan, the team behind Lavash the Book made a stop in Sarnaghpyur to pay Spartak Aslanyan a visit. Aslanyan makes clay tonirs (a subterranean oven) using a process that probably hasn't changed much in centuries. And since tonirs play fundamental roles in making traditional lavash, we wanted to see how they're made. What we learned: you can do a whole lot with just a little.
