The dough is never rolled with a pin — vendors flatten each disc by hand into a roti far thicker and larger than an ordinary wheat one, a technique passed down through generations of local cooks.
Black gram (mashkalai) and rice are ground into flour, mixed into a firm dough, and hand-flattened into thick, hearty discs cooked on a clay griddle until browned. Roadside stalls across Rajshahi and Chapainawabganj sell it hot with mashed eggplant, dried chili, and fried meat on the side.
