It's nicknamed 'pathar ki roti' — stone bread — because the dough is baked wrapped directly around a heated stone, and the finished loaf comes out hard enough to keep for weeks without spoiling.
Wheat dough is flattened around a fire-heated stone and baked in a tandoor until it hardens into a dense, chewy loaf, sometimes flecked with sesame seeds. It's the standard bread served alongside sajji at Balochistan's roadside grill stalls, torn apart to scoop up the meat.
