When the Spanish explorers arrived in Mexico, the natives offered them a chocolate drink cooled with snow (from the mountains) and mixed with vanilla as a sweetener, since chocolate, by itself, is bitter.
In Europe, too, chocolate was served along with vanilla for more than a century after arriving from the New World. Then people started using sugar instead of vanilla to sweeten the chocolate; vanilla became a flavor on its own.
All the vanilla consumed in the world was grown in Mexico until 1836, when scientists found a way to grow it in other lands. Today, most of the world's vanilla comes from Madagascar and other islands in the Indian Ocean.
Vanilla comes from an orchid - which is the only orchid on Earth that produces a useful product.
