Awadhi chicken dum biryani is a flavorful and aromatic rice dish that originated in the Awadh region of India. It is made by marinating chicken in a blend of spices and yogurt, then layering it with partially cooked basmati rice and slow-cooking it in a sealed pot. The slow-cooking process allows the flavors to meld together, resulting in a delicious and tender biryani. The biryani is garnished with fried onions, mint, and coriander, and is best served with raita or salan.
