Vanilla is perhaps best known as the world's favourite ice-cream flavour. But next to saffron, it is the most 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 who's travelled the world seeking out vanilla's rich history, and by Rose Elliot, who'll be making her easy real vanilla ice-cream.
