‘Red Gold’ Saffron (Kesar): Key Properties, Health Benefits and Culinary Uses of the GI-Tagged Spice

Saffron is one of those things that sounds almost unbelievable when you first hear about it. The world's most expensive spice, sometimes called ‘Red Gold’, comes from the tiny dried threads inside a small purple flower called Crocus sativus. In India, people call it Kesar. In Kashmir, it goes by Zafran. To get just one kilogram of this spice, farmers have to pick from around 75,000 flowers, all by hand. That's the simple reason it costs so much.

India grows most of its saffron in a place called Pampore, a plateau in the Kashmir Valley. People there have been growing saffron for more than 2,500 years, so this isn't something new. It's deeply rooted in the region's culture, farming traditions and daily life.

GI Tag and Kashmiri Saffron

In 2020, the Government of India gave Kashmiri Kesar a Geographical Indication (GI) tag. Think of it like a certificate that says, this product comes from this specific place and that place is what makes it special. The GI tag helps separate genuine Kashmiri saffron from cheaper versions sold from Iran or Spain. It also means farmers in Kashmir can sell their saffron at a better price, because buyers know they're getting the real thing.

Kashmir's location plays a big role here. The region sits at an altitude of 1,600 to 1,800 metres. The winters are cold, summers stay dry and the soil drains well. These natural conditions are hard to replicate anywhere else and they result in saffron that has higher levels of the compounds responsible for its colour, smell and taste compared to saffron grown in other parts of the world.

Key Properties of Saffron

What makes saffron taste, smell and look the way it does comes down to three main compounds found in the spice. The first is crocin and its related compound crocetin. These are what give saffron that beautiful golden-yellow colour when you dissolve it in water or add it to food. The second is safranal, which gives saffron its warm, honey-like smell that's hard to describe but impossible to forget. The third is picrocrocin, which adds a mild bitterness and gives the spice its complex, layered flavour.

When you're looking at saffron threads, good quality ones should be deep red in colour with slightly yellow tips. They should smell strong and release a rich golden colour when soaked in warm water. International standards (called ISO 3632) actually grade saffron into four categories based on how much colour it produces, from the highest grade called Coupe down to below standard.

Health Benefits of Kesar

People in Ayurvedic, Unani and Persian medicine traditions have been using saffron as a remedy for thousands of years. What's interesting is that modern science is starting to back up many of these old beliefs.

Antidepressant Effects

Some well-conducted studies have found that saffron extract works as well as low-dose antidepressants for people dealing with mild to moderate depression. It seems to work by influencing how the brain handles serotonin, a chemical closely tied to mood. That said, anyone on medication should check with their doctor before using it as an alternative.

Antioxidant Activity

Crocin and crocetin are strong antioxidants, meaning they help the body fight damage caused by free radicals. This matters because free radical damage is linked to ageing, heart disease and cancer. Regular consumption of saffron in food is thought to support better overall health at a cellular level.

Cognitive Health

This is where things get particularly interesting. Researchers studying patients with early-stage Alzheimer's disease found that taking saffron supplements led to improvements in memory and thinking skills comparable to certain medications. It's still early research, but the signs are genuinely promising.

Eye Health 

Crocetin has shown some ability to protect the cells in the eye responsible for vision, particularly in age-related macular degeneration, one of the most common causes of vision loss in older people.

Anti-inflammatory and Anticancer Potential

Lab studies have shown that saffron's active compounds can reduce inflammation and even slow the growth of certain cancer cells. Human clinical trials are still ongoing, so this area needs more research before firm conclusions can be drawn.

Culinary Uses

This is where saffron really earns its place in homes and kitchens around the world. In Indian cooking, it shows up in Kashmiri pulao, saffron-infused phirni (a creamy rice pudding) and the beloved biryani, where it adds both colour and fragrance. Many families across India also make kesar doodh, warm saffron milk, as an everyday health drink.

Beyond India, saffron is central to Spanish paella, Persian rice dishes like chelow and pilaf, Italian risotto Milanese and Moroccan tagines. It also finds its way into sweets, ice creams and breads across the Middle East and South Asia.

One important tip: never just throw saffron threads directly into a hot dish. Instead, soak them in warm water, milk or broth for around 15 to 30 minutes first. This step, called blooming, draws out the full colour, aroma and flavour from the threads. It makes a noticeable difference in the final dish.
