How much saffron should I use?

Fifteen to twenty threads serve four people. Saffron is counted in threads rather than spoons, and a gram holds roughly four hundred and fifty of them. Going over deepens the colour but not the dish; past a point every extra thread adds more bitterness than colour.

Do you have to soak saffron before using it?

Yes. Steep crushed threads in two tablespoons of warm water, milk or stock for about twenty minutes before adding them to the dish. Colour extracts best at around 55 to 60°C and breaks down faster above about 70°C.

How should saffron be stored?

Airtight, dark, cool, and nowhere near the stove. Kept dry, saffron does not spoil in a way that makes it unsafe; it fades. Storage studies have recorded colouring strength falling by half within the first year, and faster still in light and damp air.

How to Use Saffron: How Much, How to Bloom, How to Store

Chapter 01 · The one rule

How do you bloom saffron?

Crush the threads, steep them in two tablespoons of warm liquid for twenty minutes, then pour the whole thing, liquid and threads, into the dish. This is called blooming.

The reason is simple. The colour sits inside the thread and is water-soluble. Dropped dry into hot oil it scorches; dropped into a boiling pot it gives up its colour unevenly and its aroma to the steam. Steeping draws much of it out first, and the rest finishes releasing in the dish.

Warm, not boiling. Colour extracts best at around 55 to 60°C, and breaks down faster above about 70°C.

01 · Crush: Between the fingers, or ground with a pinch of sugar or salt so the threads do not stick to the mortar
02 · Steep: 2 tbsp warm water, milk or stock. Hot to the touch, not boiling extraction studies put the useful window at roughly 55 to 60°C
03 · Wait: 20 minutes. The liquid turns deep gold
04 · Use it all: Threads included. straining them out throws away what you paid for
In a hurry: Ten minutes will do. Two will not

Chapter 02 · The measure

How much saffron should you use?

Fifteen to twenty threads for four people. That is the honest answer, and it sounds too small to be worth the price, which is exactly why it's so easy to use too much. Saffron is counted in threads, not spoons. A gram holds roughly four hundred and fifty, and fewer when the threads are thick and whole.

Going over deepens the colour but not the dish. It makes it bitter, and at real excess it turns metallic and medicinal. Saffron is one of the few ingredients where restraint is not thrift but technique.

Rice for four: 15 to 20 threads, bloomed
Machboos or biryani, for six: 20 to 30 threads, bloomed in warm stock
Milk and desserts: 15 to 30 threads per litre
Tea: 4 to 5 threads per cup. Let it sit five minutes
Qahwa: 3 to 4 threads per pot
Ice cream: About 100 threads per litre

Chapter 03 · The liquid

What should you bloom saffron in?

Whatever the dish is already made of. The bloom carries into the dish, so the liquid should belong there.

Warm water

The default, and the one that shows you most clearly how good your saffron is. Use it for rice, for stews, and whenever you want nothing between you and the saffron.

Start here

Warm milk

For desserts, puddings and anything set or frozen, where the bloom should belong to the dish rather than sit on top of it. Note that water draws the colour out most cleanly; milk carries more of the scent. If you want the most colour from the fewest threads, bloom in water and add the milk after.

For sweets

Warm stock

For machboos, biryani and pilaf. Take two tablespoons out of the pot, let it cool for a minute, bloom in that, and return it at the end so the colour sits on the surface of the rice rather than disappearing into it.

For rice

Rose water

A Gulf and Persian habit, and a good one, but it is a strong partner. Start with half rose water, half plain, or it will argue with the saffron rather than carry it.

With care

Chapter 04 · Threads, powder or extract

Which format should you reach for?

NeedsBest for

Threads20 minutes to bloomRice, stews, anything where you want to see the threads

PowderNo long bloom; dissolve in a spoon of warm liquidDough, batter, drinks, even colour through a mixture

ExtractNothing, a few dropsTea, desserts, service at speed, consistent colour every time, if stored as directed

One warning worth repeating: powder is the easiest format to adulterate, because once saffron is milled you cannot judge it by eye. Buy powder only from a house that will show you the ISO 3632 report for the powder itself, not just the threads it came from. See the Grading School before you buy any of it.

Chapter 05 · Keeping it

How should you store saffron?

Airtight, dark, cool, and nowhere near the stove. Kept dry, saffron does not spoil in a way that makes it unsafe. It fades, and colour goes first and most measurably: storage studies have recorded colouring strength falling by half within the first year, and faster still in light and in damp air.

This is the whole argument for a harvest year on the jar. “Best before” tells you when a seller stopped being responsible. A harvest year tells you how old the saffron actually is, which is the best available number for predicting how it will perform tonight.

Container: Airtight. The original jar, lid closed properly
Light: A cupboard, not a window ledge or an open rack
Heat: Never above or beside the stove, the worst shelf in the kitchen
Fridge: Unnecessary in a cool kitchen. In a hot one, a sealed jar in the fridge beats a warm cupboard; let it reach room temperature before opening
Freezer: Only sealed, and only if you will not reopen it often
The real clock: The harvest year on the jar, and how you've kept it since

Chapter 06 · The five mistakes

What goes wrong most often?

01

Adding dry threads to a hot pan

The most common and the most expensive. The outside scorches before the inside releases anything. Bloom first, every time.

02

Using too much

A generous hand is a virtue with most spices and a fault with this one. Past a point, every extra thread adds more bitterness than colour.

03

Boiling the bloom

Warm liquid draws the colour out. Boiling liquid drives the aroma off into the room, which smells wonderful and does nothing for dinner.

04

Straining out the threads

A bloomed thread still holds colour and aroma. Unless the dish must be perfectly smooth, put them in.

05

Keeping it for a special occasion

Saffron fades in the jar whether or not the occasion arrives. A two-year-old jar saved for a wedding is weaker than a fresh one used on a Tuesday.

Now cook with it

Fifteen threads, twenty minutes, and a jar with its harvest year on the label.
