The History and Culinary Magic of Saffron: The World’s Most Expensive Spice

Rachel Roddy has adapted Richard Olney’s classic recipe for saffron and tomato rice, a dish uniting a precious spice with ripe tomatoes.

The Labor and Logistics Behind the Spice

Saffron commands an exorbitant price for a reason. Derived from the crocus flower—which features six lilac-purple flowers, three yellow stamens, and three orange-red stigmas—the spice demands exhaustive manual labor. Workers must pick the thread-like stigmas by hand only when the flowers are fully open, a finicky procedure unchanged since ancient times.

To prevent color and flavor degradation, these delicate threads must undergo immediate drying, a step that reduces their total weight by roughly 80 percent. Cultivators require tens of thousands of fiery filaments to yield just half a kilogram of the dried product. This intense labor dynamic directly shapes the commercial strategies of modern producers such as David Smale, a geophysicist by training who now cultivates English saffron commercially.

Historical Roots and Cultural Diffusion

The cultivation of saffron spans centuries and continents. Native to Crete, Iran, and south-west Asia, the crop has served medicinal, cosmetic, and culinary purposes since the dawn of civilization. Alan Davidson notes in The Oxford Companion to Food that Moguls brought the use of saffron from Persia to India, specifically to Kashmir. Meanwhile, the Arabs cultivated the crop in Spain by AD960, with cultivation eventually spreading to Italy, France, Germany, and England by the 13th century.

Historical records trace English production to towns like Chipping Walden in Essex, where women known as “crokers” harvested the purple blooms on damp September mornings, eventually prompting a name change to Saffron Walden. Archival documents from the University of Cambridge record commercial thefts of saffron from warehouses and druggists as late as 1871, underlining the historical value of the commodity.

Preparing Richard Olney’s Classic Saffron Rice

Roddy’s adaptation of Olney’s recipe emphasizes proper extraction techniques to maximize flavor. David Smale notes that after infusing the strands in warm liquid, the saffron threads should turn very pale as the color leaches out, adding that roughly ten strands suffice for an exquisite culinary effect. The dish pairs a base of butter and olive oil with onions, long-grain rice, light vegetable stock, and slivers of peeled, ripe tomatoes.

The preparation process requires precision in the kitchen:

• Melt butter and olive oil in a heavy-based casserole over medium-low heat.
• Add finely diced onions and a pinch of salt, cooking for 10 minutes until softened.
• Stir in the long-grain rice and the saffron with its soaking water until the grains glisten.
• Pour in vegetable stock or water, reduce to a gentle simmer, cover, and cook for 18 to 20 minutes until tender.
• Fold in separately peeled, ripe tomatoes.
