Amchur (Dried Green Mango)
What it is
Unripe (green) mango, sliced, sun-dried, and ground into a pale tan, fibrous, fruity-sour powder (amchur / amchoor, from aam "mango" + chur "powder"). The dried slices themselves are sometimes used whole.
How it's made
Hard green mangoes are peeled, sliced thin, sun-dried until leathery and pale, then ground; the unripe fruit's high acidity is what's being captured and concentrated.
Flavor profile
Sour, tangy, and fruity with a faint resinous, slightly sweet-bitter edge — citrus-like tartness plus an unmistakable green-mango character (from the unripe fruit's acids). Like sumac, it is a dry souring agent: it sharpens a dish and adds a hint of fruit without any liquid.
Culinary uses
A North Indian and Pakistani staple — the tang in chaat masala, in samosa and aloo fillings, dals, marinades and tandoori rubs, and dry-cooked vegetable dishes (sabzi) where you want acidity but not the moisture of lemon or yogurt; also a meat tenderizer (the unripe fruit's enzymes). Pairs with cumin, coriander, chile, black salt (kala namak), and chickpeas.
Regional variations
North Indian amchur is the dominant form; some regions use the whole dried mango slices (amchur "petals") in cooking and then remove them.
Cultural & historical context
Amchur is a thrift-and-ingenuity spice — a way to use the abundant unripe mangoes of the pre-monsoon season and to carry sourness through the year in a dry, storable form. It exemplifies the South Asian preference for specific sour notes (amchur vs tamarind vs lime vs pomegranate vs kokum vs yogurt), each chosen for the exact kind of acidity and body a dish needs — a granularity of souring that Western cooking, which often defaults to lemon or vinegar, rarely matches.
