Understanding Smoke Points in Cooking Oils

Smoke point is a practical cooking number, not a health rating. Here is how to use it.
What smoke point means
The smoke point is the temperature at which an oil starts to visibly smoke in the pan. Past that point, flavour deteriorates quickly.
It varies by oil type, by how refined the oil is, and even between batches.
Matching oil to method
Gentle sautéing, tempering and everyday curries sit well below most oils' smoke points. Very high-heat frying is where the number matters most.
A simple rule: if the oil smokes, the pan is too hot. Lower the flame rather than pushing through.
Practical habits
Heat oil only as much as the recipe needs, avoid reusing oil repeatedly, and never leave oil unattended on high heat.
Frequently Asked Questions
- Do unrefined oils have lower smoke points?
- Generally yes, because natural particles and compounds remain in the oil. Cook at moderate heat and watch the pan.
