Amchoor

• amchurअमचूर

  Hindi

  Literally dried unripe mango. It is a souring agent, not a fruit flavouring, and it does not taste of ripe mango.

Sharply sour with a fruity, faintly resinous background and a slight astringency. It is more purely acidic than sumac and less sweet than tamarind, and it hits immediately rather than building.

Faintly fruity and resinous, with a sharp sour edge. Much quieter than its taste, which is unusual and worth knowing — a smell test underreports it.

Pale fawn to light beige, sometimes distinctly yellow where turmeric has been used during drying. A fine, slightly fibrous powder.

A fine powder that can be slightly fibrous. It dissolves into a wet dish and stays visible as a dusting on a dry one.

• Citric and malic acids — The sourness, at a concentration far above ripe mango because the sugars that would balance them have not developed.
• Terpenes and carotenoid breakdown products — The faint resinous fruitiness behind the acid, and what distinguishes amchoor from a bare acidulant.

Add it late and taste as you go. Amchoor is doing one job — sourness without liquid — and prolonged cooking dulls exactly the acidity it was added for, so it belongs near the end or off the heat. Half a teaspoon sours a dish for four, and brands vary enough in acidity that the quantity is worth checking rather than assuming. Its real advantage shows in dry dishes and marinades: a spiced potato sabzi or a dry chana wants sourness and would be ruined by the water in lemon juice, and a meat marinade sours and browns better without it. Do not toast it, and do not bloom it in fat; it scorches and turns bitter for no gain.

Chana and chickpea dishes, aloo and vegetable sabzis, samosa and pakora fillings, chutneys, marinades for meat and paneer, and chaat masala, where it is the souring component. It works with chickpeas, potato, cauliflower, okra, paneer, lamb and pastry, and alongside cumin, coriander seed, chilli, black salt and asafoetida. Its distinctive use is in dry dishes and marinades, where lemon juice would add water the cook does not want.

• grinding — Already a powder in most retail forms. Whole dried slices are ground to order in some kitchens and are noticeably fresher.
• blooming — Not bloomed in fat. Amchoor is added late, off the heat or near it, because prolonged cooking dulls the acidity that is its entire purpose.
• boiling — Simmered in a wet dish it disperses well and softens, which suits a chana or a chutney; a long boil flattens it.
• toasting — Not toasted. It scorches and turns bitter, and there is nothing to be gained.

Taste a pinch rather than smelling it. Amchoor is much quieter in the nose than on the tongue, so a smell test underreports it badly — fresh powder is sharply sour with a fruity edge, and old powder is sour and flat. Colour helps too: fawn is right, brown is old.

• A solid cake rather than a loose powder
• Brown rather than fawn colour
• Bare sourness with no fruit behind it

• Moisture uptake and caking, which is the dominant practical failure
• Loss of the fruity aromatic fraction, leaving a bare sourness
• Slow darkening of the powder from fawn towards brown

Powder for most people, slices if you use it rarely. This is one of the few spices where the ground form is the sensible default — amchoor is used as a powder in nearly every dish that calls for it, and grinding hard dried slices is more trouble than it is worth for half a teaspoon. Buy a small jar, keep it genuinely dry, and expect to replace it within a year; the acidity lasts but the fruit character does not, and a caked jar is the usual end. If you cook with it two or three times a year, slices from a South Asian grocer are the better purchase.

• Pale fawn and loose rather than brown or caked.
• A sharp sour taste when a pinch is tasted, with a fruity edge behind it.
• A short ingredient list — dried mango, and turmeric at most. Added acidulants or starch are a different product.
• Whole dried slices in preference to powder if you use it rarely, since they keep roughly twice as long and can be ground to order.

No consumer grade exists. Commercial specification covers acidity, moisture and cleanliness, none of which reaches a retail packet, so colour and taste do the work.

Anacardiaceae

A large evergreen tree of South Asia, grown across the tropics for its ripe fruit. Amchoor uses the windfall and thinned green fruit that would otherwise be wasted, which is much of why it is inexpensive.

South Asia, where the mango is native and where essentially all amchoor is produced.

• India — major producer. Overwhelmingly the largest producer, chiefly in the northern mango-growing belt.
• Pakistan — notable producer
• Bangladesh — notable producer

Green fruit collected from thinning and windfall in the pre-monsoon months, before any ripening has begun.

1. Collecting green fruit — Unripe mangoes gathered from thinning and windfall.Why: Acidity is highest and sugar lowest before ripening starts.
2. Peeling and slicing — Fruit peeled, stoned and cut into thin slices.Why: Thin slices dry evenly; thick ones spoil in the centre.
3. Sun drying — Slices sun-dried over several days until hard and pale, sometimes with a turmeric dusting to deter insects.Why: The turmeric is functional and also the reason some amchoor is more yellow than others.
4. Grinding — Dried slices milled to a fine fawn powder. Whole dried slices are also sold and used directly in some dishes.

No consumer grade. Commercial quality turns on colour, acidity, moisture and freedom from grit and fibre.

Recorded risks are starch and flour bulking, which is easy to hide in a pale powder, and added acidulants standing in for the fruit acidity. Excess fibre from poorly sieved material is a quality rather than a fraud problem.

Not cultivated for its own sake. Amchoor is made from unripe fruit thinned from mango trees grown for the ripe crop, and from windfall, which makes it a by-product rather than a crop.

Tropical and subtropical, with a reliably dry period for sun-drying the sliced fruit. Rain during drying spoils a batch.

A preservation solution that became an ingredient. Drying unripe fruit that would otherwise be wasted is an old and widespread practice in South Asia, and amchoor is the version that became a spice in its own right rather than a means of storing mango.

A regional product traded chiefly within and from South Asia, and inexpensive because it is made from fruit that has no other market.
