Kolkata Biryani is a unique variation of biryani that originated in the city of Kolkata, India. It is made with fragrant basmati rice, meat (usually chicken or mutton), and a special blend of spices. What sets Kolkata Biryani apart is the addition of potatoes and boiled eggs, which add a unique flavor and texture to the dish. The biryani is cooked with a generous amount of ghee (clarified butter) and is known for its subtle flavors and distinct aroma.
