Vanilla Flowers and the Helping Human Hand
The flavor of vanilla comes from a long, thin pod. That pod grows on a vine, a kind of orchid. To get a pod, a flower must first be pollinated. Pollen has to move from one part of the flower to another.
In the place where vanilla first grew, a small native insect did this job. In many other places, that insect does not live. So farmers must pollinate each flower by hand.
Each vanilla flower opens for only a single morning. A worker has to find it and use a small stick to move the pollen at just the right time. If the worker misses the morning, there will be no pod. A farmer may check hundreds of vines each day.
When the pods are picked, they are green and have almost no smell. They are warmed, left to sweat, and dried in the sun over many weeks. Slowly they turn dark brown and wrinkled, and the rich smell grows stronger.
Hand work and long waiting are why real vanilla costs more than many other flavors.
