Saffron Crocus sativus
The most expensive spice on earth by weight, and the one most often faked. Buy threads, never powder, and steep them before they go anywhere near the pan.

In the kitchen
A pinch is a real measurement
Twenty threads will season a paella for six. Saffron is one of the few spices where more genuinely makes a dish worse — past a point the bitterness and the medicinal edge take over.
Steep, then add the liquid too
Bloom the threads and pour the coloured liquid into the dish along with them. Most of what you have extracted is in that water; tipping it away is the most common way people waste saffron.
Toast the threads first, lightly
A few seconds in a dry warm pan until they are brittle, then crumble and steep. It makes them easier to break up and lifts the aroma. Watch closely — they scorch almost instantly.
Beyond the kitchen
A STERILE TRIPLOID
Crocus sativus cannot reproduce sexually and does not exist in the wild. Every saffron crocus on earth is propagated by dividing corms, which makes the entire global crop a set of clones descended from an ancient Cretan selection.
THE BRONZE AGE FRESCOES
Saffron gatherers are painted on the walls of Akrotiri on Santorini, in frescoes dating to around 1600 BCE — among the earliest depictions of any spice being harvested anywhere.
DYE AND PIGMENT
Saffron was used as a textile dye for royal and religious garments across the ancient world, and as a pigment in manuscript illumination. Its use as a status colour long predates and often outweighed its use as a flavour.
FAKED FOR CENTURIES
Adulteration with safflower, turmeric, marigold and dyed fibres is as old as the trade. Fifteenth-century Nuremberg operated the Safranschou code, under which merchants caught adulterating saffron could be fined, imprisoned or executed.
A longer history
Saffron cultivation appears to originate in Bronze Age Crete or the surrounding Aegean, where the frescoes at Akrotiri depict its harvest around 1600 BCE. Because the plant is sterile, its spread everywhere since has depended on people physically carrying corms.
It moved through Persia, which became a major producer and remains the largest today, and through the Arab world into Spain, where Moorish agriculture established the cultivation that still underpins Spanish saffron and dishes such as paella. Medieval Europe traded it at extraordinary prices, and the fourteenth-century Saffron War over a stolen shipment is a genuine historical episode.
Production remains overwhelmingly manual. The flowers open for a short window, must be picked at dawn, and the stigmas are separated by hand the same day. Iran produces the great majority of world supply, with Kashmir, Afghanistan, Spain, Greece and Morocco making up most of the rest.
ADULTERATION
Saffron is the most commonly faked spice in the world. Powder is the highest-risk form and should simply be avoided. Genuine threads are trumpet-shaped, deep red rather than uniformly orange or yellow, and colour water slowly over several minutes — an instant burst of colour usually means dye. Buy from a supplier who states the origin and grade, and treat a low price as the warning it is.
