In our series premiere, I travel to the humid, emerald forests of Madagascar to find the "Ghost" of the spice world: Wild Orchid Vanilla. I explore why the vanilla you know is actually a high-stakes clone, and why the original, wild ancestors are disappearing. I’ll show you the incredible secret of "marriage by hand"—the human labor required to keep this flavor alive—and what the world loses if this orchid finally fades into a memory.
