Vanilla got a bad rap somewhere along the way. It became a synonym for plain, bland or ordinary.

Yet vanilla may be the world's most exotic spice and most alluring scent. 

That means it's also expensive. Vanilla currently costs around $300 per pound. And, like every other food, vanilla prices have skyrocketed in recent years and months. 

Among spices, only scintillating saffron routinely costs more, industry experts say.

Vanilla is native to Central America and was enjoyed by Mesoamerican cultures. It was brought to Europe with cacao by Spanish explorers following Columbian exploration.
