Eight of the World's Most Expensive Ingredients
Most Expensive Spice: Saffron
What: Saffron is derived from a type of crocus that grows most extensively in the Mediterranean and Middle East. Its brightly hued threads are graded for quality by the Switzerland-based International Organization for Standardization (ISO), which ranks the product on a scale from 0 to 250 based on color, fragrance, and taste.

However, saffron is pungent enough that a little bit goes a long way: The 15 to 20 threads used in a typical paella recipe weigh in at only a very small fraction of a gram.
Why Pay More: The labor-intensive picking, cleaning, sorting, and toasting of these tiny saffron stigmas is to blame for the staggering price tag. It takes a football field–size plot of saffron crocuses to produce just 1 pound of saffron threads, which must be picked immediately upon blooming.
