Biryani, Biriani, Beryani or Beriani is an South Asiandish that comes in set of rice-based foods made with spices, rice (usually basmati) and meat, fish, eggs or vegetables. The name comes from the Persian word beryā(n) which means "fried" or "roasted".[1]
The cooking method of Biryani came from Iran. It was brought to the Indian subcontinent by Iranian travelers and merchants. In India and Pakistan, the recipe of biryani developed to its current form. Local variants of this dish are popular not only in South Asia but also in Bangladesh, Southeast Asia, Arabia, and within various South Asian communities in Western countries.
Biryani and pullao are different. In biryani the rice (plain or fried) is cooked separately from the thick sauce (curry of meat or vegetables). The curry and the rice are then brought together and layered. This makes a dish with contrasting flavors of rice, sauce and meat or vegetables.
