Flaxseed oil

Flaxseed oil also makes a really strong bond to your skillet and is full of health benefits.

It also gets dry quickly and is used by many people for seasoning.

It forms a smooth, strong, and fine covering.

But it is not much recommended because of its much lower smoke temperature of 107 degrees Celsius, characteristic odor, and high-priced budget.

Seasoning skillets using this oil takes a lot of time.

Avocado oil is amazing for seasoning a cast iron skillet because it has an extremely high smoke temperature of 271 degrees Celsius.
