By the late 18th century, a ton of Mexican vanilla was worth … “its weight in silver.”
That’s just one of the fun facts I learned from Robert Krulwich’s rendering of the bittersweet story of the slave boy on the Indian Ocean island of Réunion who discovered how to manually pollinate vanilla. Or did he? Well, that’s the point of the story. If you read the whole thing over at National Geographic’s blogs, you also get the benefit of some really charming drawings.
