07 Applying oil

Clean the uncoated cast iron cookware thoroughly to remove any dust or debris. Once clean and dry, apply a thin layer of vegetable oil evenly across the entire surface, both inside and out. You can use a paper towel or a soft cloth to ensure the oil is spread uniformly.

08 High-temperature baking

Preheat your oven to about 450-500°F (232-260°C). Place the oiled cookware upside down on the middle oven rack, with a baking sheet or aluminum foil on the lower rack to catch any oil drippings. Bake the cookware for about an hour.

After the hour has passed, turn off the oven and allow the cookware to cool down completely inside the oven. The high heat bakes the oil into the cast iron, creating a non-stick, protective layer that becomes more robust with each use.
