Chettinad Dum Biryani is a spicy and flavorful biryani recipe from the Chettinad region of Tamil Nadu, India. It is made with fragrant basmati rice, tender meat (chicken or mutton), and a blend of spices that give it a unique taste. The biryani is cooked in layers, with the rice and meat cooked separately and then layered together. It is then sealed and cooked on low heat, allowing the flavors to infuse and the meat to become tender. The result is a biryani that is aromatic, spicy, and has a perfect balance of flavors.
