Kolkata Biryani, also known as Calcutta Biryani, is a popular recipe from the city of Kolkata in India. It is a unique variation of biryani that combines the flavors of Mughlai and Awadhi cuisines with a touch of Bengali influence. Kolkata Biryani is made with fragrant basmati rice, tender meat (usually chicken or mutton), and a blend of spices including cloves, cinnamon, and cardamom. The biryani is cooked in a dum style, where the rice and meat are layered together and slow-cooked to perfection. Kolkata Biryani is known for its subtle flavors, use of potatoes, and the addition of boiled eggs. It is often served with a side of raita and aloo dum (spicy potato curry).
