The dishes like tandoori chicken may have started during in the Harappan civilization. According to famous archeologist and vice-chancellor of Deccan College Professor Vasant Shinde, the earliest proof for a dish like tandoori chicken can be found in the Harappan civilization in 3000 BC. His team has found ancient ovens at Harappan sites which are similar to the tandoors that are used in the state of Punjab. Physical remains of chicken bones have also been found along with burn marks. According to Sushruta Samhita, the meat was cooked in an oven (kandu) after marinating it in spices like black mustard (rai) powder and fragrant spices. According to Ahmed (2014), Harappan oven structures may have operated in a similar manner to the modern tandoors of the Punjab.
