Before we get into the details, firstly you need to understand the basic idea behind seasoning. How it works and why is it important? Knowing about it all will help you figure out the best oil. So let us understand the whole concept of seasoning and see which oil would be best suited for it.

The Concept Of Seasoning

A cast iron is much like a simple piece of iron molded into a cookware shape without seasoning. Iron alone, it is very reactive thus cooking straight on to it would burn your food and the pan itself as well which would leave you with a rusted pan.

To protect the iron pan from getting rusted, it is important to season it properly with the help of cooking oils. Here the term seasoning does not mean adding salt and taste to your food. Instead, seasoning is the term used to describe the layering process of cast iron.

Oils with fats like consistency such as grapeseed oil and flaxseed oil are used to form layers on top of the iron base to create a clear coating to protect it from burning. The seasoning process is actually what gives it the non-stick properties.

How Oil Bonds With Iron – The Chemical Reactions

Everything around us takes place due to chemical reactions. Whether it is rainfall or that sound of your beef steaks getting prepared on a cast iron pan. Cast iron pans are seasoned with the help of chemical reactions as well.

In this case, when hot oil is heated on an iron pan, a chemical reaction takes place between the iron particles of the pan and the molecules of oil. In scientific terms, the reaction is known as polymerization. During the process, the oil molecules react with iron and form a new compound that has a plastic-like consistency that develops a layer on the iron base.

The seasoning process is carried out multiple times. When enough layers of oil have been seasoned on the cast iron pan, overall coating takes the form of a black skin-like layer that protects the metal from rusting when heated at high temperatures. Not only does seasoning keep your cast iron protected but also provides non-stick properties to it which allows you to prepare sticky food on the pan with ease.

How to Season Your New Cast Iron Pan?

After finding out about the chemical reaction, you might be thinking that seasoning a cast iron pan is something only professionals can do. But that is not true. You can season your very own cast iron pan at home as well.

Most cast iron pans that you buy from the market are pre-seasoned. The reasons being that the manufacturers pre-season the pan, to, make it safe and secure for shipping and packaging. But at the same time, they also make it ‘out of the box’ ready for the end-user.

But in case, you have an old pan which is rusting out a bit and you wish to season it properly then in such as case, you will only need a few things and it would be done on its own. To season your pan at home, you will need the following items;

  • An Oven (Any other heat source may also work)
  • Seasoning oil (You can use grapeseed oil or flaxseed oil)
  • Paper towels to pat the base dry.

To carry out the process, simply add seasoning oil to your pan. Use a paper towel or your hand to add oil to the pan’s surface. Make sure it is evenly spread out and no part is left unattended. Once done, place the pan in the oven for around an hour and heat it at 350 degrees Fahrenheit.

Once the pan is properly heated and the layer of oil has been set on the top of the cast iron, simply use paper towels to wash away the excess oil on the pan which is left behind. Repeat the process to form a thick layer that will not only protect the pan but will also add flavor to your food.

Make sure to leave a window open or a door open, in case you put it on the flame or any other heat source. You don’t want the smoke to gather up in your kitchen. Make sure that it leaves as it can be a bit dangerous for breathing as there are chemical reactions taking place. Other than that, you should have no trouble seasoning your cast iron at home using our recommended seasoning oil.
