Kolkata Biryani, also known as Calcutta Biryani, is a unique biryani variant that originated in the city of Kolkata, India. It is influenced by the flavors of Mughlai and Awadhi cuisines. The key ingredients in this biryani are basmati rice, meat (usually chicken or mutton), potatoes, and a blend of spices. The rice and meat are cooked separately and then layered together. The biryani is then garnished with fried onions, boiled eggs, and a sprinkle of biryani masala. Kolkata Biryani is known for its distinct taste and is often served with a side of raita or salad.
