Myth vs fact: is there one best oil for everything?

Every few months a new listicle crowns a new champion — “the one oil you should be cooking everything in” — and every few months the crown moves. Coconut had a run. Then olive. Then rice bran. The myth underneath never changes: that somewhere out there is a single best oil, and you just have to find it. We press thirteen different oils, so you might expect us to nominate one of ours. We will not, because the premise is wrong.

Why can’t one oil be best for everything?

Because “best” changes with the job. An oil is not one thing — it is a bundle of properties, and different dishes call on different ones:

• Heat tolerance. Deep-frying pooris demands an oil that holds serious temperature — unrefined mustard manages 250°C / 482°F. Flaxseed falls apart at roughly 107°C / 225°F and must never see a flame. Neither fact makes either oil “better”; they are different tools. Our smoke point table maps all thirteen.
• Fat profile. Some of our oils are MUFA-dominant, some carry mostly PUFA, one is nearly all lauric-acid MCTs — and the honest reading of the science is that variety across the week serves you better than loyalty to any single profile. We explain the vocabulary without the hype in our plain-language fats guide.
• Flavour. This one the listicles always forget. Mustard’s pungency is the point of achaar. Coconut’s sweetness is the point of thoran. Groundnut’s neutrality is the point of a bhajiya batter that should taste of onion. An oil that is “best” in a laboratory is useless if it argues with your dinner.

What did Indian kitchens do before the listicles?

They rotated — without ever calling it that. Mustard country in the North and East, groundnut and sesame in the West, coconut and gingelly in the South; sesame in winter, lighter oils in summer; ghee for the festive fry and the dal tadka. Region, season and dish each pulled a different bottle off the shelf. The tradition never crowned one oil, and its instinct — different fats for different jobs, variety across the year — is precisely where sensible modern advice has landed too.

So what should a practical kitchen actually stock?

Not thirteen bottles. Three roles cover nearly everything:

1. An everyday oil for sabzi, tadka and shallow frying — groundnut and sesame are the classic candidates; coconut if your kitchen leans coastal.
2. A high-heat oil for the occasional deep fry — mustard, or ghee when the occasion is festive.
3. A raw finisher for chutneys, salads, raita and drizzles — flaxseed or almond, kept small and fresh.

Rotate within the roles when a bottle empties — white sesame this month, groundnut the next — and the variety takes care of itself without a single decision being agonised over. Our compare-oils page puts every candidate side by side, and if you enjoy the traditional lens, the dosha quiz adds Ayurveda’s opinion about which oils suit your constitution — tradition’s answer to the same rotation question.

Verdict

Myth. There is no one best oil — not ours, not anyone’s — and a brand that names its own bottle as the answer to every dish is marketing, not advising. The honest answer has three bottles in it, used for what each does well, swapped around as the seasons and the menu turn. The good news: that is also the answer that makes food taste best, and it is the one your grandmother’s kitchen already knew.
