Biryani is a popular rice dish in Kolkata, known for its rich flavors and aromatic spices. It is made with basmati rice, meat (such as chicken, mutton, or fish), and a blend of spices. The dish is cooked in layers, with the meat and rice being cooked separately and then combined. Kolkata biryani is known for its distinct flavor, which comes from the use of potatoes and a special blend of spices. It is often served with raita (yogurt sauce) and a boiled egg on top.
