From a flower in Kashmir comes a precious spice, journey of saffron

Men, women and children stoop as they laboriously pick the delicate flowers and place them in wicker baskets. They next separate the purple petals by hand, and from each flower comes three tiny, delicate stigmas which are then dried in the sun, becoming one the most expensive and sought-after spices.

Across the world, saffron is used in products ranging from food to medicine and cosmetics. A kilogram (2.2 pounds) requires the stigmas of about 150,000 flowers and can easily sell for $3,000-$4,000.

In Kashmir, the spice is a source of pride and has fueled the region's economy and culture for centuries. But over the years its cultivation has faced troubles due to climate change, poor irrigation facilities and imports of cheaper Iranian saffron. Strife in the region has also impacted its production and export.

To boost saffron's cultivation and export, authorities in Kashmir have set up a high-tech spice park to increase production quality and quantity. But very few farmers find the latest technology lucrative and most still use century-old techniques for picking and drying the saffron.

Most of Kashmir's saffron is grown in Pampore, a tiny town south of the region's main city, Srinagar.In Kashmir, the spice is mostly used in Kehwa, a slow-brewed sugary green tea infused with spices like cinnamon and cardamom and garnished with almonds. Saffron is also used in Wazwan, a traditional Kashmiri wedding meal cooked by special chefs that includes more than 30 dishes.
