Every Indian grandmother has an aam ka achaar recipe. It is never written down. It lives in muscle memory. A pinch of this. A handful of that. Sun it for “enough” days.

This recipe puts that knowledge on paper. With exact measurements. Step-by-step instructions. And the storage science that makes it last 6 months or more.
This is the traditional Punjabi-style aam ka achaar. Raw mangoes. Mustard oil. And spices roasted in the sun. The way it has been made for generations.
What You Need
Ingredients (Makes About 1 kg of Pickle)
- Raw green mangoes: 1 kg (firm, sour, no soft spots)
- Mustard oil: 250 ml (cold-pressed, kachi ghani)
- Salt: 100 gm (rock salt or sendha namak is best)
- Turmeric powder: 2 tablespoons
- Red chilli powder: 3 tablespoons (Kashmiri for colour, regular for heat)
- Mustard seeds (rai): 3 tablespoons
- Fenugreek seeds (methi dana): 2 tablespoons
- Fennel seeds (saunf): 2 tablespoons
- Nigella seeds (kalonji): 1 tablespoon
- Asafoetida (hing): 1 teaspoon
Equipment Needed
- Clean, dry glass jar (1.5–2 litre capacity)
- Clean muslin cloth or cotton towel
- Dry cutting board and knife
- Dry spice grinder or mortar-pestle
- Dry mixing bowl (steel or glass, not plastic)
Step-by-Step Recipe
1 Choose the right mangoes. Pick raw, green, firm mangoes. They should be sour and hard. No soft spots. No ripe smell. The best varieties for achaar are Rajapuri, Totapuri, and local desi kairi. Season: March to May.
2 Wash and dry the mangoes. Wash under running water. Wipe with a clean towel. Let them air dry for 2–3 hours. There should be zero moisture on the surface. This is critical.
3 Cut into pieces. Cut the mangoes into medium-sized pieces. Keep the skin on. Remove the seed. Each piece should be about 2–3 cm. Use a dry knife on a dry cutting board.
4 Sun-dry the mango pieces. Spread the cut pieces on a clean cloth or steel plate. Place in direct sunlight for 4–6 hours. Cover with a thin muslin cloth to keep flies away. Do NOT cover with a lid — moisture needs to escape. This step removes excess water from the mangoes.
5 Prepare the spice mix (masala). Dry roast mustard seeds, fenugreek seeds, fennel seeds, and nigella seeds on low heat for 2–3 minutes. Let them cool fully. Grind coarsely in a dry grinder. Do not make a fine powder — coarse texture is traditional. Add turmeric, chilli powder, hing, and salt. Mix well.
6 Mix mangoes with masala. In a large, dry bowl, combine the sun-dried mango pieces with the spice mix. Use clean, dry hands or a dry spoon. Toss until every piece is well coated.
7 Heat the mustard oil. Heat the oil in a pan until it reaches smoking point. This removes the raw, pungent taste of mustard oil. Turn off the heat. Let it cool to room temperature. Never add hot oil to the mangoes — it will cook them.
8 Combine oil and pickle. Pour the cooled oil over the mango-masala mixture. Mix thoroughly. Every piece must be coated in oil. The oil acts as a preservative.
9 Transfer to a sterilized glass jar. Pack the pickle into the jar. Press down gently. Pour extra oil on top so it forms a layer at least 1 cm thick. This oil seal is what keeps air and moisture out.
10 Sun cure for 5–7 days. Keep the sealed jar in sunlight for 5–7 days. Shake or stir once daily. Sunlight helps the masala penetrate the mango. It also warms the oil, which speeds up the curing process.
Common Mistakes (And How to Avoid Them)
| Mistake | What Goes Wrong | How to Fix |
|---|---|---|
| Using wet mangoes | Fungus grows within days | Always sun-dry for 4–6 hours |
| Not enough salt | Pickle spoils quickly | Use at least 10% salt by weight |
| Not enough oil | Mold on top | All pieces must be submerged in oil |
| Using raw (unheated) oil | Strong pungent taste, spoils faster | Always heat oil to smoking point first |
| Plastic container | Oil leaks, staining, chemical leaching | Use glass jars only |
| Wet spoon in jar | Fungus within a week | Always use a dry spoon. Keep a dedicated one. |
| Covering during sun-drying | Moisture trapped, no curing | Use muslin cloth, not a tight lid |
How Long Does Aam Ka Achaar Last?
| Storage Method | Shelf Life | Conditions |
|---|---|---|
| Glass jar, room temperature | 6–12 months | Cool, dry place, oil layer on top |
| Fridge | 12+ months | Oil may solidify but that is normal |
| Poor storage (plastic, wet spoons) | 2–3 weeks | Fungus likely |
Glass Jar vs Plastic for Achaar Storage
| Feature | Glass Jar | Plastic Container |
|---|---|---|
| Reacts with acid? | No | May leach chemicals |
| Staining | Easy to clean | Permanent turmeric yellow |
| Oil leaking | Rare (good seal) | Common (lids warp) |
| Airtight seal | Excellent | Degrades over months |
| Shelf life of pickle | 6–12 months | 2–3 months max |
Regional Variations
Every state in India has its own style:
- Punjabi style: Heavy mustard oil, coarsely ground spices, sun-cured. This is the recipe above.
- Gujarati style: Sweeter, uses jaggery and less oil. Lighter in spice.
- South Indian (avakaya): Uses groundnut oil instead of mustard oil. More chilli, less fennel.
- Rajasthani style: Extra sour mangoes, heavy on red chilli and mustard.
- Bengali style: Panch phoron (five-spice blend), lighter on oil.
All styles follow the same science: salt draws out moisture. Oil seals out air. Spices add flavour and some act as natural preservatives.
P.S. — The Right Jar for Your Achaar
Glass jars make achaar last 3–4 times longer than plastic. The InstaCuppa Stainless Steel Airtight Container (Rs 1,999) has a silicone gasket that blocks air and moisture completely. The built-in date tracker helps you remember when you made the batch.
For see-through monitoring, the InstaCuppa Glass Bottle range lets you check oil levels and colour without opening the lid.
Frequently Asked Questions
How long does homemade aam ka achaar last?
In a clean glass jar with enough oil and salt, aam ka achaar lasts 6–12 months at room temperature. In the fridge, it can last over a year. The key is using dry spoons and keeping the pickle submerged in oil.
Which mangoes are best for achaar?
Use raw, green, firm, sour mangoes. Rajapuri, Totapuri, and local desi kairi work best. The mango should have no soft spots and no ripe smell. Season is March to May in India.
Why does my achaar get fungus?
The most common cause is moisture. Wet mangoes, wet spoons, or a jar that was not dried properly all introduce water. Water feeds fungus. Dry everything thoroughly. Keep pickle submerged in oil.
Can I skip the sun-drying step?
It is not recommended. Sun-drying removes moisture from the mango pieces, which prevents fungus. It also helps spices cure properly. If you cannot sun-dry, air-dry indoors for 8–10 hours near a fan.
How much salt to use in mango pickle?
Use at least 10% salt by weight of the mangoes. For 1 kg of mangoes, use 100 gm of salt. Rock salt (sendha namak) is preferred. Too little salt causes quick spoilage. Too much makes it too salty.
Why is mustard oil heated to smoking point?
Heating removes the raw, pungent taste of mustard oil. It also kills any bacteria in the oil. Always let the oil cool to room temperature before adding to the pickle. Hot oil will cook the mango pieces.
Can I store achaar in plastic containers?
It is not recommended. Plastic reacts with the acid in pickles and may leach chemicals. Plastic stains permanently from turmeric. Glass jars with airtight lids are the safest choice for long-term pickle storage.
When is the best time to make mango pickle?
March to May, when raw mangoes are in season and there is strong sunlight for sun-drying and curing. Making achaar in monsoon season is risky because humidity causes spoilage.
