– The cast iron skillet – A box of vegetable shortening, which can be purchased in your favorite supermarket for less than $2. – A roll of heavy paper towels – Your oven
Make sure your new cast iron cookware has been washed in hot water and mild dish soap.
Fold the paper towel into a fourth and place a dollop of vegetable shortening in the skillet.
Once you have the skillet coated, place it in the oven (at 200 degrees) and set a timer for 3 hours.
