The most important thing you need for good flavoring is best oil for Cast Iron Seasoning. For flavoring purposes, you need oil with a low smoke point, which can rapidly oxidize and carbonate on heat. This is due to the burning oil that forms a non-stick coating on the surface of cast iron cooking equipment. And then you will find best oil for Cast Iron Seasoning.
However, low smoke oils are best comparing to high smoke points such as peanut, sunflower, saffron, or soybean oil when it comes to excellent and proper flavoring.
If you want to use nut or vegetable oils, they must refine. The simple answer can remain on smoke at high temperatures is to use the best oil for processing cast iron cooking tools.
What is Cast Iron Seasoning?
Cast iron is a solid and light metal, especially a weird blend for a cooking process. The metal is physically stable but highly reactive; meaning even a drop of water sitting on your cast iron pot can leave a rusty spot. To protect that nice black surface, you need to coat it with a thin layer of hardened oil called seasoning.
To get a well-processed pan, you pour oil inside the cooking surface and then heat it until the fat polymerizes, repeating the process of creating a protective layer.
Polymerized oil is more like plastic than fat, which makes it harder and more resistant to sticking. By heating the whole pan to a high temperature, you connect the oil permanently to the raw iron. In this form, it protects the metal from wind and food.
Modern pans, unlike vintage items, always pre-processed. This is a great feature. Most people do not have modern pans. It does mean you do not need to learn how to season cast iron. So when the surface decays, they don’t know how to re-season.
Fortunately, the process is very easy. Once you season it again, the pan will be almost brand new. But you have to follow a few steps first.

Coconut oil is the right solution for cast iron flavoring if you do not often cook at high temperatures.
3) Yandilla Grade All Natural Mustard Oil
Blends of soybean oil, beeswax, and palm oil should not go fragile. It smelled like honey during the flavoring process. The disadvantage is that the fried chicken took up quite a bit of its flavor and the pan was dull after cooking with the tomatoes.
The mustard oil is tough to move around the corner of the pan. With a still-hot pan, Things melt a little soon as the oil hits the pan.

It dries naturally and is an excellent perk for iron casting, which is very sensitive to any moisture.

Cast iron seasoning with butter is a simple, tasty way to season your pan with regular use, but you want to make sure you are using real unsalted butter.
Margarine or butter substitutes are not good options for cast iron flavoring. You always want to avoid using anything salty to season your dish. However, it can cook with salt.
Using butter as a first seasoning may not even give you a black appetite like some of the oils on this list, but it will develop nicely over time. Crisbee Stik is a best option, but if you have butter and use it a lot in your cooking, it will work.
Ghee is very similar to butter, with one big exception: it has a very high smoke point. The butter hits the high end of the optimum cooking temperature at 300F. The ghee will retain heat up to 475F. However, it still doesn’t even offer a season. Depending on your preferences, you may rate them differently.
