Kolkata Biryani is a unique and flavorful biryani recipe from the city of Kolkata, India. It is made with fragrant basmati rice, tender meat (usually chicken or mutton), and a blend of spices that includes saffron and rose water. The biryani is cooked in a special technique called 'dum', where the pot is sealed with dough to trap the steam and infuse the flavors. The result is a biryani that is aromatic, flavorful, and has a distinct Kolkata-style taste.
