Ghee's smoke point is usually given as about 250°C, a figure a 2024 review puts above most other edible oils, and it smokes far later than butter because clarification removes the milk solids that scorch. That headroom is real, but it matters in a narrower set of situations than the marketing suggests, and in most of them, expensive ghee is the wrong ghee to use.
Smoke point is the temperature at which a fat starts to break down visibly and give off acrid smoke. It is one of the few genuinely useful numbers in cooking fats, and one of the most misapplied, because a high smoke point is treated as a quality mark when it is really just a property.
At a glance
- A 2024 review in the Journal of Ayurveda and Integrative Medicine gives ghee's smoke point as about 250°C; we could not find the laboratory measurement behind the figure.
- Butter scorches long before its fat smokes because of its water and milk solids; ghee has had both removed.
- Free fatty acid content was the strongest predictor of smoke point across 48 virgin olive oils in a 2025 study, which is why any fat, ghee included, smokes lower as it ages.
- Smoke point matters for deep frying, hard searing and tadka. For simmering, sautéing, baking and finishing it is irrelevant.
- Frying is where a premium ghee's aroma and carotene are destroyed, so use an inexpensive fat for heat and good ghee where you taste it.
Why is ghee's smoke point so much higher than butter's?
Because clarification removes the two things that make butter burn. Butter is at least 80 per cent milk fat with up to 16 per cent water under FSSAI's standard, and the rest is milk solids, mostly protein and lactose. When butter is heated, the water boils off and the solids brown and then scorch, long before the fat itself would smoke.
Making ghee cooks off the water and separates out those solids. What remains is close to pure butterfat, at least 99.5 per cent milk fat by the same standard, and butterfat on its own is stable to a much higher temperature. The figure usually quoted, and repeated in the 2024 review, is about 250°C. Any real figure will vary with how thoroughly the ghee was clarified and how fresh it is, as the table and the later sections explain.
| Fat | What smokes or scorches first | What the figures say |
|---|---|---|
| Butter | Water and milk solids | Scorches well before its fat would smoke |
| Virgin olive oil | Free fatty acids | 157°C to 215°C across 48 Spanish oils in a 2025 study, falling as free acidity rose |
| Refined vegetable oils | Free fatty acids, reduced by refining | Higher and more consistent smoke points than virgin oils, the same study notes |
| Ghee | Free fatty acids, once the solids are gone | About 250°C in a 2024 review; no laboratory measurement found |

Where does the smoke point actually matter?
In three situations: deep frying, where fat sits at high heat for a long time; hard searing and tadka, where a dry pan gets very hot very fast; and anything left unattended on a high flame, where headroom is a margin for error. For everything else the fat never approaches its smoke point and the number is irrelevant.
- Deep frying. Oil sits at frying heat for a long time. A fat with headroom above that degrades more slowly.
- Hard searing and tadka. Spices dropped into hot fat need it hot enough to bloom without the fat itself burning.
- Anything left unattended on high heat. Headroom is a margin for error, which is a real benefit in a busy kitchen.
Simmering, sautéing, baking and finishing never get close. Most home cooking, including most Indian home cooking, is far gentler than frying heat, as how to use ghee in cooking, dish by dish sets out.
Should you deep fry in good ghee?
You can, but the reason not to is economic rather than culinary. What makes a premium ghee worth its price is aroma, carotene and the fatty acid profile that comes from what the animal grazed on. Aroma compounds are volatile, which is what makes them aroma, and prolonged high heat drives them off. Carotene degrades too.
After twenty minutes at frying temperature, an expensive single-origin ghee and a commodity one are much closer than the price difference suggests. The sensible arrangement for most kitchens is two fats: something inexpensive and stable for frying heat, and a smaller jar of good ghee used where you can taste it. That costs less overall, and you notice the good one more when it is not competing with a deep fryer.
Where does good ghee earn its price?
Where it goes in late and stays recognisable: a spoon stirred into dal at the end, over hot rice, on roti, into halwa, laddoo or panjiri, or in a tadka poured over at the finish. In all of these the ghee is barely heated or heated briefly, the aroma survives intact, and the difference between a good ghee and an indifferent one is immediately obvious.
This is worth saying plainly because the category rarely does: premium ghee has a narrower useful range than its marketing implies. Buying it and then destroying it in a fryer is the most common way people conclude that expensive ghee is a con.
How do you keep ghee from degrading?
Three habits cover most of it: do not reuse fat that has smoked, keep water out of the jar, and keep the jar dark and closed. Each one slows the build-up of free fatty acids, which is the process that lowers a fat's smoke point and, eventually, turns it rancid.
- Do not reuse fat that has smoked. Breakdown products accumulate with each heating cycle, and a fat that has been pushed past its smoke point repeatedly is measurably worse than fresh. Never tip used cooking fat back into the main jar.
- Keep water out of the jar. A wet or previously used spoon introduces moisture, and moisture is what lets ghee spoil. Ghee keeps at room temperature precisely because it is nearly dry.
- Keep it dark and closed. Light and air oxidise fats. Glass with the lid on, out of direct sun, is enough; refrigeration is unnecessary and makes it awkward to use. How to store ghee covers the rest.
Free fatty acid content, which is one of the lines on a batch report, is essentially a measure of how far this process has already gone. A low figure on a fresh batch means the ghee was well made and well handled before it reached you. Ours are published per batch on the lab reports page.
Does the smoke point tell you anything about quality?
Only indirectly. A poorly clarified ghee with milk solids left in it will smoke lower, so a very low smoke point does suggest sloppy production. But the reverse does not hold: a high smoke point does not indicate good ghee. A heavily refined, blended or even adulterated fat can smoke high, because refining is precisely what raises smoke points.
In other words, smoke point tells you how a fat behaves in a pan. It tells you nothing about what the animal ate, whether the ghee was churned from curd or separated from cream, or whether anything was mixed into it. For that you need the yield ratio and a batch-coded report, which is what six checks before you buy is about, and our own ghee is on the A2 bilona ghee page.
Does ghee's smoke point change as it ages?
Yes, downward. Smoke point falls as free fatty acid content rises; in the 2025 olive oil study it was the strongest predictor. Free fatty acids are fat molecules that have broken away from their glycerides and are far more volatile than intact ones, and they accumulate over time, faster if the ghee is exposed to heat, light, air or moisture.
So the figure of about 250°C describes fresh, well-clarified ghee, not the jar that has been next to your hob since spring. A jar opened daily for six months in a warm kitchen will smoke lower than the same ghee did when it was sealed. This is another reason free fatty acid appears on a batch report: it is the number that tells you where the ghee started, and how much margin it had before your kitchen began using it up.
The practical implication is small but real. If you are frying at the top of the range, do it with fresher fat. If a jar has been open a long time, move it to finishing duty rather than frying duty.
What about tadka specifically?
Tadka is the one technique where the smoke point and the flavour question collide. Blooming whole spices needs fat hot enough to release their aromatic compounds, hot enough that cumin sizzles and darkens within seconds, so a fat with a low smoke point scorches before the spices are ready. But the tadka is poured over the finished dish, so you taste the fat directly.
The way to have both is timing. Heat the ghee until it shimmers rather than smokes, add the spices, and take the pan off the heat as soon as they colour, usually well under a minute. The fat spends very little time at temperature, the spices bloom, and the ghee's own aroma survives to reach the plate. Cooking a tadka slowly on low heat wastes the spices; cooking it until the ghee smokes wastes the ghee.
The short version
Ghee's smoke point is usually given as about 250°C, because clarification removed the water and milk solids that make butter burn, and it falls as the ghee ages. That headroom is genuinely useful for frying, searing and tadka, but frying is exactly where a premium ghee's advantages are destroyed. Use an inexpensive fat for heat, good ghee for flavour, and keep water out of the jar.
