The Food Programme: Where Do Pistachios Really Come From?

They’re in your chocolate, your gelato, even your coffee - pistachios really are everywhere at the moment. But their story goes much further than simply what turns up on our plates. Where do pistachios actually come from? From Iran, often seen as their historic home, to the vast farms of the United States, this programme traces the journey of a small nut with a surprisingly big global story.
