Ingredient

Amchur

Unripe green mango, dried and ground to a pale, fibrous powder. It sours a dish without adding liquid, which is why North Indian cooking reaches for it in dry curries and chaat where a squeeze of lemon would loosen everything.

Sourcing
Any South Asian grocer, in small packets. Rare in supermarkets outside a well-stocked world-food aisle.
Varieties
Powder, Dried slices
Quality cues
Sandy beige and loose. Dark brown or caked amchur has taken on moisture and lost most of its sourness.
Substitutions
Lemon juice, Tamarind paste, Sumac
Storage
Airtight and dry — it clumps readily. Keep it away from the steam of the hob.
Shelf life
About 1 year
