What it is

A spice made from the dried stigmas of Crocus sativus.

Plain-language buying tip

Buy whole threads when possible so the ingredient is easier to inspect; use a stated origin and lot information when a seller provides it.

Forms and use

Bloom a small pinch in warm water, stock, or milk before adding it to rice, broths, baking, or desserts.

Common forms include whole threads, ground. Match the form to the job: bloom whole threads in warm water, stock, or milk before adding them to the dish, rather than straining them back out.

Storage

Threads: one to two years at full aroma; usable at reduced strength for about three. Saffron does not rot, it thins out, and the honeyed top note goes first while the bitterness stays — which is why old saffron can make a dish taste medicinal.
Light is the main cost: Keep it in an opaque tin or a jar inside a cupboard, tightly closed. The little glass vials it is often sold in are for display; move it or keep it in the dark.
Dry, not cold: Saffron is sold at very low moisture and it will pick up damp readily. Do not refrigerate it in a home kitchen; condensation clumps the threads and dulls them.
Gone when: the threads are pale brick-orange rather than deep red with orange tips, they crumble to dust at a touch, and warm water draws out colour slowly and smells of very little. Live saffron colours warm water within a couple of minutes and smells sweet and hay-like across the room.
A quick honesty test: drop a few threads into cool water. Real saffron colours the water yellow-gold over several minutes while the threads themselves stay red. Dyed substitutes release red or orange colour quickly and the strands go pale.

Quick questions

What should I check before buying Saffron?

Check the stated botanical identity or style when available, the form, and the ingredient list. These details are more useful than relying on a broad category name alone.

Substitutions

There is no substitute for saffron's flavour: It should be said plainly, because most substitution lists suggest turmeric and that advice is wrong. Saffron is hay, honey, a faint metallic bitterness and a floral top note. Turmeric is earthy and bitter. They share a colour and nothing else.
For colour only: turmeric, safflower ("Mexican saffron", bastard saffron) or annatto will give a yellow-orange. Use a small amount — enough for colour, not enough to flavour — and do not describe the result as a saffron dish.
If you are short: use less saffron properly rather than more of something else. A dozen threads bloomed in warm liquid for twenty minutes will do more for a paella than a teaspoon of turmeric.
Threads over powder: buy threads. Powdered saffron is the easiest spice in the world to adulterate, since colour and weight can be faked with dyed safflower, turmeric or worse, and once it is powder you cannot see what you bought. A thread has a distinct trumpet-shaped end.
No reliable weight-for-weight ratio: exists between grades, and grading systems vary between sellers, so buy by smell and appearance rather than by a grade name alone.

Pairings

Ingredients: rice, onion, garlic, tomato, olive oil, butter, cream, milk, eggs, white wine, sherry, lemon and orange, honey, almond, pistachio, rose, cardamom, cinnamon, black pepper, fennel, bay, paprika, chickpeas, fish and shellfish — mussels, clams, prawns — chicken, lamb, potato, leek, fennel bulb, winter squash, yoghurt.
Dishes: paella and other saffron rices, risotto alla milanese, bouillabaisse and fish stews, a mussel broth, chicken tagine, biryani, saffron buns and breads, kheer and rice pudding, a saffron-and-honey custard, a poached pear.
Go carefully: bloom it. Crush the threads and steep them in a few tablespoons of warm — not boiling — liquid or milk for fifteen to thirty minutes before adding them, or you will have paid for aroma that stays locked in the thread. And use less than you want to: too much saffron is bitter and faintly iodine-like, and it is the most expensive mistake in the cupboard.
