A few threads of saffron give biryani its golden streaks and unmistakable perfume. Because it is the world’s most expensive spice, it pays to know how to buy the best saffron – and how to avoid fakes. Each thread is the hand-picked stigma of the crocus flower, and it takes thousands of flowers to make a few grams.
What to Look For When Buying Saffron
- Threads, not powder: powdered saffron is easy to mix with cheaper spices. Whole threads are easier to check.
- Deep red colour: top-grade saffron is mostly red with little or no yellow style attached.
- Grade: look for “Category I” under the ISO 3632 standard, which measures colour, aroma and flavour strength.
- Harvest date: saffron is best within about two years of harvest.
- Packaging: airtight, light-proof tins or dark glass protect the aroma.
Types of Saffron
- Iranian (Persian): the largest producer. Grades such as Negin and Sargol are all-red threads with strong colour.
- Spanish: “La Mancha” saffron has a protected origin; “Coupé” is the top all-red grade.
- Kashmiri: prized in India for its deep aroma, especially the Mongra grade, and traditional in Mughlai biryani.
- Afghan: increasingly well regarded, often good value for all-red threads.

How to Spot Fake Saffron
- Water test: drop a thread into warm water. Real saffron slowly releases a golden-yellow colour over several minutes and the thread stays red. Fakes colour the water red instantly or fall apart.
- Shape: real threads are trumpet-shaped at one end. Shredded flowers, corn silk or dyed fibres don’t have this shape.
- Smell: real saffron smells sweet, floral and a little like hay; it tastes slightly bitter, not sweet.
- Price: if it is very cheap, it is almost certainly not pure saffron.
How to Use Saffron in Biryani
Crush a generous pinch (about 15–20 threads) and soak in 3–4 tablespoons of warm milk for 15 minutes. Drizzle over the top layer of rice before you seal the pot for dum. Pair it with aged basmati rice for biryani and a spoonful of good ghee.
Frequently Asked Questions
How much saffron do I need for biryani?
About 15–20 threads (a generous pinch) is enough for a biryani for 4–6 people. Always soak it in warm milk or water first.
Why is saffron so expensive?
Each crocus flower has only three stigmas, which are picked by hand. It takes many thousands of flowers to make a small amount of saffron.
How long does saffron last?
Stored airtight in a cool, dark place, saffron keeps its best flavour for about two years.
