What is a seasoning?
It is the process of treating surfaces of cookware pieces using heated fats to enhance a stick-resistant and corrosion-free coating.
Seasoning entails a process known as polymerization. Heat cause fats to react and form polymers which are larger molecules. As a result, there is a production of free radicals that cross-link to make a thick layer on the cookware surfaces. However, it would help if you baked your pan to enhance the results and your oils have to reach a certain smoking point.
The chemistry behind seasoning simply involves changing the molecular structure of oils by heat on the surface of the cast-iron pan. The final results make your skillet non-stick, giving it a comfortable, and natural cooking surface and prevents it from rusting.
What is the Smoking Point of Oils?
The smoke point of oils represents the temperatures at which oils seize shimmering, and smoking starts. It is also known as the burning point of the oil. Low points start at 325F, and high points stand at 520F.
Why is oil smoke point so important while seasoning? Seasoning requires high temperatures; hence it needs you to use oils with a high smoking point. After the oil has reached its smoking point, fatty acids are released through a smoke.
While seasoning, oils with a higher smoking point will give the best results. When such oils are baked above their smoking point, it triggers the release of free radicals on the pan’s surface and binds with iron to form a thick coating.
Why is Olive Oil Not the Best for Seasoning Cast Iron Pan?
The average smoking point of olive is at 325-375F, which is low compared to an oil such as Soybean Oil, which is at 450F. The low smoking point makes olive oil burn so efficiently and produces a bad flavor on your food while cooking with the skillet after seasoning. Moreover, the higher the temperatures you heat a skillet, the better the seasoning.
However, you can use olive oil but expect less effective results. What is the drawback of using olive oil to season cast iron pans? When a pan seasoned with olive oil is exposed heated beyond the smoking point, the oil layer easily wears off, making the pan sticky. Do you want to cook on a sticky skillet and burn food?

It has a high smoking point of 465F; hence you will not experience the above-highlighted issues after seasoning. Using the ordinary olive is not the best choice, and it will require you to season your cast ion pan repeatedly due to the ineffective results of seasoning.
