Dan Saladino explores culinary cultures and world religions to find out how the date became one of the earliest, most revered, and diverse of all cultivated fruits, and also a feature of Christmas.

Some of the world's historically important date palm oases have survived in the south of Tunisia. Dan travels to the ancient cities of Gafsa and Tozeur to visit two of them and watches the date harvest underway. There he tastes Tunisia's most prized date, the Deglet Nour, which translates as 'fingers of light' because of it's amber colour and almost translucent appearance. In Tozeur he also explores Eden Palm, the site of of a museum dedicated to dates and date palm, where he hears how the date has been an important food and source of trade for thousands of years.

Featuring food historian Ivan Day, food writers Yasmin Khan, Itamar Srulovich and Nawal Nasrallah, archeobotanist Professor Dorian Fuller, and scientist Shahina Ghazanfar.

Produced and presented by Dan Saladino.
