The primary ingredient in biryani is rice, typically basmati rice, which is known for its long grains and aromatic qualities. Biryani is a mixed rice dish that originates from South Asian cuisine and often includes a variety of spices, meat (such as chicken, mutton, or beef), and sometimes vegetables or dried fruits. The dish is prepared by layering marinated meat and partially cooked rice, then cooking it together to blend the flavors. Each region has its own unique version of biryani, showcasing local ingredients and culinary traditions.
