Vanilla
Vanilla (Vanilla planifolia Andrews) (Family: Orchidaceae) is the only edible orchid fruit and is the world's second most expensive spice after saffron. Native to Mexico, vanilla is now cultivated in tropical regions worldwide. The beans (pods) undergo a complex curing process to develop the characteristic flavour and aroma attributed to vanillin.
Vanilla is grown as a climbing vine and requires hand pollination in most cultivation regions outside its native Mexico (where it is pollinated by native bees and hummingbirds). India cultivates vanilla in Kerala and Karnataka. The crop demands meticulous post-harvest curing over several months to produce the prized cured beans used in food and flavouring industries worldwide.
