Biryani is a set of rice-based foods made with spices, Basmati rice and meat, fish, or vegetables.
Pulao is a dish in which a rice is cooked in a seasoned broth. The English term pilaf is borrowed directly from Turkish, which in turn comes from (Classical) Persian polo, Urdu pulao, and Hindi pulav.
The difference between biryani and pulao is that while pulao may be made by cooking the items together, biryani is used to denote a dish where the rice is cooked separately from the thick sauce (curry of meat or vegetables). The curry and the rice are then brought together and mixed resulting in a dish of the contrasting flavors of rice (which has a hint of the aromas and juices of the curry) and intensely flavored sauce and meat or vegetables.
All Rice items served with Onion Chutney and Raitha.
