Cast iron, demystified: seasoning and everyday care
Cast iron has a reputation for being fussy. It isn't. Five minutes of understanding turns it into the most forgiving pan you own.
People are scared of cast iron, and they shouldn't be. The "rules" sound strict, but they come down to one idea: keep a thin layer of oil baked onto the metal. Do that, and you've got a naturally non-stick pan that outlives every coated one.
What "seasoning" actually is
Seasoning isn't a spice — it's a layer of oil that's been heated until it bonds to the iron, forming a smooth, slick surface. Most good pans come pre-seasoned, so you can cook on day one. Every time you cook with a little fat, you add to it.
The everyday routine
- Cook as normal — fat is your friend here.
- Rinse with warm water while the pan is still warm. A little soap is fine.
- Dry it completely — ideally back on the hob for a minute.
- Rub a few drops of oil over the surface, then wipe off the excess.
The only real enemies are long soaks and putting it away damp. Both invite rust.
If it does rust
Don't panic and don't bin it. Scrub the rust off, wash, dry, and re-season by baking on a thin coat of oil. Cast iron is almost impossible to truly ruin — which is exactly why it gets handed down through generations.
Why it's worth it
A cast iron skillet sears steak better than almost anything, moves from hob to oven without a thought, and gets better the more you use it. One pan, decades of meals.
