Saffron

Saffron is a spice obtained from the dried stigmas of Crocus sativus, a flowering plant in the iris family, Iridaceae. The plant is related to ornamental crocuses but is a distinct species cultivated for its spice. It grows from an underground corm and produces purple flowers, usually in autumn. Each flower has three red-orange stigmas, the thread-like structures that receive pollen.

These delicate stigmas must be collected by hand and then dried, which helps explain why saffron is one of the most expensive spices by weight. Crocus sativus does not normally produce fertile seeds, so the plant is propagated by dividing its corms. Its long history of cultivation is associated with regions around the Mediterranean and parts of western and central Asia.

Saffron is valued for its distinctive aroma, slightly bitter taste, and ability to give foods a golden-yellow color. Its main characteristic compounds include crocin, which contributes much of the color, picrocrocin, which contributes bitterness, and safranal, which is important for its aroma. Only a small quantity is generally needed in cooking.

The spice is used in dishes such as rice preparations, soups, sauces, breads, desserts, and some traditional drinks. Saffron should not be confused with turmeric, another spice that can color food yellow but comes from a different plant. Because genuine saffron is costly, lower-quality products or substitutes may sometimes be sold under similar names. For culinary use, the value of saffron lies mainly in its concentrated color, flavor, and fragrance.
