Kolkata Biryani is a unique variation of biryani that originated in the city of Kolkata in India. It is made with basmati rice, 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 a unique flavor and texture to the dish. The meat is marinated in a mixture of yogurt and spices, then cooked with partially cooked rice in layers. The dish is then cooked on low heat, allowing the flavors to meld together. Kolkata Biryani is known for its distinct taste and is a favorite among biryani lovers.
