The short answer
Do not throw it away. Achaar oil is already infused with spice. Use it for a tadka on daal, brush it on parathas, toss it with boiled potatoes or chana, add it to marinades, or drizzle a little over raita or chaat.
Ways to use it
- Daal tadka: heat a spoon of achaar oil, add garlic, pour over daal.
- Paratha: brush on instead of plain ghee.
- Chana or aloo chaat: toss with onion, lemon and chaat masala.
- Marinades: mix with dahi for chicken or fish.
- Fried eggs: fry them in it.
Keep it clean
Use a dry spoon, and store leftover oil covered. As long as it smells good and shows no mould, it is fine to use.
