Curry

The BBC reports:

In other words, had you been washed ashore four millennia ago on the banks of the now lost river of Saraswati and hitched a bullock cart ride to Farmana in the Ghaggar valley near modern-day Delhi, here's what you might have eaten - a curry.

For in 2010, when advanced science met archaeology at an excavation site in Farmana - southeast of the largest Harappan city of Rakhigarhi - they made history, and it was edible.

Archaeologists Arunima Kashyap and Steve Webber of Vancouver's Washington State University used the method of starch analysis to trace the world's first-known or "oldest" proto-curry of aubergine, ginger and turmeric from the pot shard of a bulbous handi (pot).
