  • Those are cherry-picked high numbers for EVOO and low numbers for canola oil. I have seen 450F/230C as a more common high end figure. I cook with sunflower oil which ranges 440F-480F and ghee which smokes at 482F.

    I would also like to note that the original discussion was about caring for and seasoning cast iron pans which occurs at temperatures close to the smoke point of the oil, not about frying or sautéing. Cast iron pans are often seasoned in the oven and even used for roasting or baking at oven temperatures exceeding 500F. I would never put EVOO into an oven like that unless it was protected (such as included in a pizza crust) but even then I would prefer to drizzle the olive oil over the pizza after baking rather than before, due to the volatility of all the aromatics.

    I have cooked plenty of times with EVOO but I would never use it for stir frying!





  • I think you’ll have the best experience if you learn what seasoning actually is and what it isn’t. Seasoning is polymerized cooking oil that’s bonded to the surface of the metal. It’s hydrophobic which protects the metal from rust. It does not actually give nonstick properties (those are due to cooking oil and proper temperature control).

    Seasoning is not burnt food, it’s not black, it’s not dry, nor does it leave marks on your finger when you rub it (only do this with a cold pan). A well seasoned pan should feel smooth and glossy and hard, not dry or powdery or gummy or sticky or greasy. When seasoned properly it does not need anything else applied, though most people apply a thin layer of oil as an extra precaution and because the oil improves the glossy appearance.

    One thing to be aware of is that overheating your pan will burn the seasoning, carbonizing it and turning it black. A burned seasoning is vulnerable to flaking off and adding charred flavours to food, as well as exposing the pan to potential rust. Lastly, exposing the pan to acids (such as white vinegar or simmering tomato sauce) will strip away the seasoning (and ruin your sauce).
