Carbon steel cookware

Carbon steel is around 1% carbon, versus 2 to 4% for cast iron, and it is formed by pressing or spinning sheet steel rather than pouring molten metal into a mold. That makes the walls thin and the pan light, with a flat base and usually a long riveted handle.

The cooking surface is the same as bare cast iron's: polymerized oil bonded to steel. There is no coating in the manufactured product at all — some pans ship with a beeswax or lacquer shipping finish that you scrub off before the first seasoning.

• Weight. Roughly two-thirds of a comparable cast iron pan, which matters when you are tossing vegetables.
• Response. Thin steel heats and cools in seconds, so turning the burner down actually does something.
• Shape. Sloped sides and a long handle make it a pan you can move food in, not just a vessel.
• Oven and grill. Same tolerance as cast iron — any temperature, any heat source.

• Heat retention. A cold steak drops a carbon steel pan's temperature more, which means slightly less crust.
• Robustness. Thin steel can warp if thermally shocked; a cast pan will not.
• Baking. The thermal mass of cast iron is what makes cornbread and skillet bread work.

1. Scrub off the factory finish. Hot water, soap and a scouring pad until the pan is bare gray steel. This step is non-optional and most first-time complaints come from skipping it.
2. Dry it completely on a warm hob.
3. Apply a very thin film of a high-smoke-point oil — grapeseed, canola, or a dedicated seasoning oil — then wipe it back off as if you made a mistake. The layer should be almost invisible.
4. Heat past the oil's smoke point and hold it there until the smoking stops: on the hob for 10 minutes, or in a 450F oven for an hour.
5. Repeat three or four times. Each pass adds a thin hard layer; thick single coats go sticky and flake.
6. Then cook in it. Frying, searing and roasting build seasoning faster than any deliberate session.

Long acidic cooking strips the seasoning and makes the food taste metallic — the same limitation as bare cast iron, and the same answer: use enamel, glass or stainless for tomato and wine. Dishwashers strip it too, so this is not a pan for a household that will not hand wash. And it needs to be dried and lightly oiled, which is thirty seconds that some people will not spend.

It also transfers iron into food like cast iron does, which means the same exception applies: not for anyone with an iron-overload condition.

Two carbon steel options at different price points, plus the cast iron alternative if heat retention matters more to you than weight.
