What is the world's most expensive spice by weight?

The story behind the answer

Saffron is the world’s most expensive spice by weight because it’s incredibly labor-intensive to produce. It comes from the crimson stigmas of the Crocus sativus flower—just three delicate threads per bloom. Each stigma must be handpicked during a brief flowering period, and it takes tens of thousands of flowers to yield a single pound, driving the price sky-high.

Known as “red gold,” saffron imparts a vivid golden color and distinctive aroma to dishes like Spanish paella, Persian stews, Indian biryani, and Italian risotto. Its signature compounds—crocin (color), picrocrocin (taste), and safranal (aroma)—make it unique. Memory tip: three tiny threads per flower add up to a fortune—hence saffron’s premium status.
