Kolkata Biryani, also known as Calcutta Biryani, is a unique variation of biryani that originated in the city of Kolkata in India. It is influenced by the flavors of Mughlai and Awadhi cuisines. The biryani is made with basmati rice, meat (usually chicken or mutton), and a blend of spices such as cinnamon, cloves, and cardamom. What sets Kolkata Biryani apart is the use of potatoes and boiled eggs, which are added along with the meat and rice. The biryani is then cooked on low heat, allowing the flavors to meld together. The Kolkata Biryani is known for its distinct taste and the combination of flavors from the spices, meat, and potatoes.
