Saffron, derived from the dried stigmas of the saffron crocus flower, has been cultivated for over 3,500 years and remains one of the most valuable spices globally. The spice is notable for the intensive labor required in its production, as the red stigmas must be carefully hand-picked or tweezed from each flower. The harvesting period is short, occurring during a few weeks in autumn, typically early in the morning. Approximately 150 flowers are needed to produce just one gram of saffron.

Historically, saffron's uses have evolved significantly. Evidence of its application as a pigment has been found in 50,000-year-old cave paintings in present-day Iran. In ancient Persia, saffron was widely used not only for dyes and perfumes but also in traditional medicine. In ancient Egypt, Cleopatra is believed to have incorporated saffron in beauty treatments, mixing it with milk.

Saffron spread to Europe during the Middle Ages through trade, where it gained a reputation as a medicinal curative, particularly during the Black Death in the 14th century. At that time, some Europeans attributed curative properties to saffron, which contributed to its heightened demand. This period also witnessed the Saffron War, a 14-week conflict triggered when a large shipment of saffron was stolen by financially troubled European nobles. The cargo was eventually recovered, but the incident encouraged several European countries to begin their own saffron cultivation.

The high value of saffron also led to stringent regulations, such as the Safranschou Code in Europe, which imposed severe penalties on those found guilty of adulterating saffron with substances like marigold petals, honey, or oil. Historical records indicate that offenders could face execution, with some reportedly burned at the stake alongside the adulterated spice.

Today, saffron remains the most expensive spice in the world, with prices ranging from US$5,000 to US$10,000 per kilogram. Iran dominates global production, accounting for around 90% of the saffron supply. In contemporary cuisine, saffron continues to be a prized ingredient, adding distinctive flavor and color to a wide array of dishes, including Moroccan tagine, Persian jewelled rice, Indian biryani, French bouillabaisse, Spanish paella, and Italian risotto Milanese.
