 According to O'Brien (2013), "the Amritsari kulcha is a crisp, flaky roti made with refined flour; it is stuffed with potato, onionblack pepper, chilli, cumin, and dried pomegranate seeds (anardana) and cooked in the tandoor".Dishes similar to tandoori chicken may have existed during the Harappan civilization.According to archaeologist 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.
