Dishes similar to tandoori chicken may have existed during the Harappan civilization. According to eminent archeologist and vice-chancellor of Deccan College Professor Vasant Shinde, the earliest evidence for a dish similar to tandoori chicken can be found in Harappan civilization and dates back to 3000 BCE. His team has found ancient ovens at Harappan sites which are similar to the tandoors so popular in the Punjab. Physical remains of chicken bones with char marks have also been unearthed. Sushruta samhita records meat being 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.
