Mustard oil is traditionally heated until it gives off a thin wisp of light smoke, then cooled slightly before the other ingredients go in. This softens its raw pungency and gives a rounder, nuttier flavour. If a dish turns bitter, the usual causes are overheated oil, burnt spices or garlic, too much oil, or stale oil.
Kachi Ghani mustard oil has a sharp aroma and a strong, pungent taste. That is exactly why it is loved in North and East Indian kitchens. But many home cooks face the same problem: the dish tastes too sharp, slightly bitter, or “raw.” Often the cause is not the oil. It is how the oil is heated and used.
If you have ever wondered “sarson ka tel garam karke kyun use karte hain?” or “sarson ke tel mein khana kadwa kyun lagta hai?”, this guide answers both. It covers why mustard oil is heated, how to do it safely, what causes bitterness, and how to use Kachi Ghani mustard oil for everyday dishes.
Why Is Mustard Oil Heated Before Cooking? (Sarson Ka Tel Garam Karna)
In many Indian kitchens, mustard oil is heated until it gives off a thin wisp of light smoke. It is then taken off the heat and cooled slightly before spices or vegetables are added.
This is a traditional practice. Cooks follow it because it mellows the raw sharpness of the oil and gives a rounder, nuttier flavour. It is common in tadka, sabzis, fish preparations and pickles.
Treat it as a flavour technique passed down through generations, not as a strict rule. If you have a health condition or dietary restriction, follow the advice of a qualified healthcare professional on how much mustard oil suits you.
What Is the Smoking Point of Mustard Oil?
Short answer: Mustard oil is generally described as having a relatively high smoke point, but published figures vary depending on the oil and how it is processed.
For home cooking, do not rely on a single number. Watch the oil instead. A thin wisp of light smoke means it is ready to be taken off the heat. Thick, dark or sharp-smelling smoke means it is overheated.

How to Heat Mustard Oil Properly: Step by Step
- Use a heavy-bottomed pan or kadhai. Thin pans heat unevenly and can burn the oil.
- Heat on a medium flame. A high flame makes it easy to overshoot
- .
- Watch for a thin wisp of light smoke. Do not wait for thick or dark smoke.
- Switch off the flame or lift the pan. Let the oil cool for a short while.
- Add your tempering or ingredients. Start with whole spices, then onion, garlic or vegetables.
Safety tips: Never leave hot oil unattended. Keep water away from the pan. Keep a lid nearby to cover the pan if the oil flares up. Handle the pan carefully while it is hot.
Why Does Food Cooked in Mustard Oil Taste Bitter or Too Sharp?
If your dish turns out harsh or bitter, check these common causes.
1. The oil was not heated, or was heated unevenly
Raw mustard oil added directly to a dish can taste very sharp. A brief heating step usually softens it.
2. The oil was overheated
Oil taken well past the first wisp of smoke can smell acrid and leave a burnt taste in the food.
3. Spices or garlic got burnt
Garlic, fenugreek seeds (methi dana) and whole spices burn quickly in hot oil. Add them after the oil has cooled slightly, and watch them closely.
4. Too much oil
Mustard oil has a strong flavour. Using the same quantity you would use for a neutral refined oil can overpower the dish. Start with a little less and adjust.
5. Old or poorly stored oil
Oil kept near the stove, in sunlight, or with the cap open can turn stale or rancid. A sour, musty or “off” smell is a warning sign. Do not use oil that smells rancid.
