Vanilla is perhaps best known as the world's favourite ice-cream flavour. But next to saffron, it is the most听costly spice on earth. Historically it is said to fetch its weight in silver.
It's also the world's most labour-intensive crop. As a result, the vanilla trade has become a lucrative and incredibly shady business, with producers employing armed guards and workers being killed for a few kilos of the substance.
Jenni is joined by Tim Ecott听who's听travelled the听world seeking out vanilla's rich history, and by Rose Elliot, who'll be making听her easy real听vanilla ice-cream.
