Hyderabadi Dum Biryani is a popular and flavorful rice dish from the city of Hyderabad, India. It is made by marinating meat (usually chicken or mutton) with spices and yogurt, and then layering it with partially cooked basmati rice. The layers are then sealed with dough and cooked on low heat, allowing the flavors to meld together and the rice to absorb the aromatic spices. The result is a fragrant and delicious biryani that is rich in flavors and textures.
