"Let's start with a spice quiz. One is a bean discovered in Mexico. One's a tree native to India. One's the seed of a fruit discovered in Indonesia."

"Today vanilla, cinnamon and nutmeg can all be found in any spice farm in Zanzibar — the East African archipelago that was used as a spice plantation by the 18th century Omani Empire."
