Kolkata Biryani is a unique variation of biryani that originated in the city of Kolkata, India. This biryani is made with fragrant basmati rice, succulent meat (usually chicken or mutton), and a blend of spices. What sets Kolkata Biryani apart is the addition of potatoes and boiled eggs, which add an extra layer of flavor and texture to the dish. The rice and meat are cooked separately and then layered together, resulting in a biryani that is both flavorful and visually appealing. Kolkata Biryani is known for its subtle flavors and is often served with a side of raita or salad.
