Traditional Hyderabadi biryani is cooked entirely by dum — sealing the pot with a ring of dough so the rice and marinated meat steam together in their own trapped heat, with no stirring or checking until the seal is broken at the table.
Basmati rice and meat marinated in yogurt, chili, and spices are layered raw together in a heavy pot, sealed with a dough lid, and slow-cooked over low heat so the rice finishes by absorbing the meat's juices rather than being cooked separately and combined. Old City stalls and biryani houses across Hyderabad serve it with mirchi ka salan and a cooling raita.
