Amchur (Dry Mango Powder): Make It at Home and Spot Fakes
Open an old packet of amchur and you’ll know at once if it has died: no sharp sour smell, just a faint dusty sweetness and lumps that won’t break. This guide shows how to make amchur (dry mango powder) at home from kacha aam, how to tell good powder from stale or doctored stuff, and where it earns its place in the kitchen.
What amchur actually is
Amchur is nothing more than unripe green mango, peeled, sliced thin, dried until it snaps, and ground. The fruit used is the hard, pale-fleshed early mango that falls in spring storms or is picked before it sweetens. As it dries, the sourness concentrates. So does a faint resinous, almost pine-like note that you won’t get from lemon or vinegar.
It gives you sourness without liquid. That’s its whole point. A dry bhindi, a tandoori marinade that mustn’t go runny, a samosa filling, a chaat masala: all want tang without wetness, and amchur supplies it.
The short version
- Raw mangoes: 1 kg hard green mangoes gives roughly 80 to 120 g powder
- Drying: 3 to 5 sunny days, or 8 to 10 hours in an oven at 60 °C
- Everyday use: 1/2 to 1 tsp for a dish serving four
- Best within: 6 months of grinding; whole dried slices last far longer

How to make amchur at home
Pick mangoes that are completely hard, with no give at the stem and no yellow inside when you cut one open. Ripening fruit dries into leathery sweet strips that refuse to powder.
- Wash 1 kg green mangoes and dry them fully with a cloth. Wear gloves or wash your hands well afterwards; the sap near the stem irritates some people’s skin.
- Peel with a sharp peeler. The peel is bitter and holds more of that sap.
- Slice the flesh off the stone into pieces 2 to 3 mm thick. Thin is everything. Thick slices stay damp in the middle and go mouldy.
- Spread the slices in one layer on a clean steel thali or a cotton cloth. Cover with a fine muslin to keep off flies and dust.
- Sun-dry for 3 to 5 days, bringing them in each evening so they don’t reabsorb night moisture. Turn them every morning.
- No strong sun? Use an oven at 60 °C with the door propped open a finger-width, for 8 to 10 hours, turning halfway.
- Test: a finished slice snaps cleanly with a dry crack. If it bends, it needs another day.
- Cool completely, then grind in a dry spice grinder in short bursts. Sieve and regrind the coarse bits.
- Store in a small airtight glass jar away from the stove.
Many families skip the grinding and keep the dried slices (called amchur ki phanki or khatai) whole. They stay lively much longer, and you can grind a few tablespoons at a time.
A darker shade is fine
Homemade amchur is usually beige to light brown, never the bright lemon-yellow of some shop packets. If a little turmeric-like glow appears, that’s the fruit. If your powder is sunshine yellow, something was added.
Spotting stale or adulterated amchur
Sour powders are easy to pad out, and cheap packets vary a lot. Use your senses before you trust the label.
| Sign | What it suggests |
|---|---|
| Sharp, fruity sour smell | Good, fresh powder |
| Flat, dusty or sweetish smell | Old, sourness has faded |
| Hard lumps, damp feel | Moisture got in; check for mould |
| Bright uniform yellow | Possible added colour |
| Gritty crunch between teeth | Possible sand or grit |
| Barely sour, very fine and silky | Possible starch or filler |
Two quick kitchen checks
Water test: stir 1/2 tsp into a clear glass of water and let it stand 5 minutes. Real amchur partly dissolves, clouds the water and slowly settles as soft fibre. Heavy grit sinking straight to the bottom is a warning. A strong coloured streak running out of the powder suggests added dye.
Taste test: a pinch on the tongue should make your mouth water within a second or two. If it tastes mostly of flour, it’s either stale or stretched.
These checks can’t prove purity. Mango itself contains some starch, so the old iodine test isn’t reliable here. Buying from a brand with a clear ingredient list, or making your own, is the honest answer.
Cooking with dry mango powder
Add amchur towards the end of cooking. Long frying scorches it and turns it bitter, and heat dulls the sourness.
- Dry sabzi (bhindi, aloo, arbi, karela) for 4: 1 tsp, sprinkled in during the last 2 minutes.
- Chana masala: 1 tsp with the garam masala near the finish, if you’re not using tamarind.
- Meat or paneer marinade: 1 tsp per 500 g along with yoghurt and spices. The acid helps the texture, and it won’t thin the marinade like lemon.
- Homemade chaat masala: 2 tbsp amchur, 2 tbsp roasted jeera, 1 tbsp kala namak, 1 tsp black pepper, 1/2 tsp dry ginger, 1/4 tsp hing. Our hing guide explains why a pinch is plenty.
- Fruit chaat: a light pinch over guava, apple and cucumber.
Out of amchur? Use about 1 tsp lemon juice for every 1/2 tsp amchur where a little liquid won’t hurt, or a spoon of tamarind pulp in a gravy. For dry dishes, crushed anardana is the closest match.
In north Indian and Punjabi kitchens, raw mango season meant rooftops lined with drying slices, and the powder was prized in the hot months for “cutting” the heaviness of oily food. Ayurvedic writing places sour tastes as appetising and digestive but warns they aggravate heat when overused. Unani tradition generally regards unripe mango as cold and dry, and some older households avoided sour foods for anyone with a sore throat or cough. These are traditional frameworks, not medical findings.
Myths worth dropping
“Amchur is full of vitamin C, so it’s as good as fresh fruit.” Raw mango does contain vitamin C, but sun-drying and months on a shelf lose much of it. Enjoy amchur for flavour; don’t count it as your fruit.
“It melts fat” or “it’s good for weight loss.” No. It’s a seasoning used by the half-teaspoon.
“Amchur causes kidney stones.” There’s no special reason to single it out at ordinary cooking amounts. If you’ve been told to follow a stone diet, follow your own doctor’s list.
Mango allergy: mango belongs to the same plant family as cashew and pistachio, and the sap and peel can cause itchy rashes around the mouth or hands in sensitive people. If raw mango or its skin has ever made you itch or swell, avoid homemade amchur prep, and seek urgent help for any lip or throat swelling or breathing trouble.
Acid reflux, gastritis, mouth ulcers: sour powders can sting. Go light, or skip it during a flare.
Pregnancy and breastfeeding: amchur in normal food amounts is fine for most people. Don’t eat it by the spoonful to chase a craving if it’s worsening heartburn, and ask your doctor about anything beyond food use.
Children: a pinch in family food is fine for children eating solids. Plain spoonfuls are harsh on young teeth.
Mouldy or damp powder: discard it. Mould on dried foods isn’t something to scrape off.
Common questions
How long does amchur powder last?
It’s at its best for about six months in an airtight jar. It won’t turn dangerous after that, but the sourness fades until it’s pointless. Dried whole slices keep their punch a year or more.
Can I dry mango slices indoors without sun or an oven?
Only in dry weather with good airflow, and it can take a week or more. In humid months, slices tend to mould before they dry, so an oven at low heat is safer.
Amchur vs lemon juice: which should I use?
Amchur for dry dishes, marinades and spice mixes. Lemon for a fresh finish on dal, salads and anything with liquid. They taste different; amchur is fruitier and slightly resinous.
Is amchur safe for people with diabetes?
In seasoning amounts it adds little to a meal. Watch the dishes it goes into, like sweet chutneys, rather than the powder itself, and follow your own diet plan.
