The Carbon Steel Wok

The nonstick wok you bought for eighteen euros will be scrap within three years. Its coating cannot survive the heat a wok is built to make.

Buy carbon steel once and that cycle stops. The euros you would have spent rebuying flimsy pans stay in your pocket and quietly compound.

The object

A carbon steel wok is one sheet of steel, spun or hand-hammered into a bowl, with a riveted steel handle. There is nothing bonded to it that can peel. Cook on it and the surface takes a seasoning. That is a thin baked layer of oil that turns the steel dark and slick.

Carbon steel is built for the high flame a stir-fry needs. Nonstick coatings break down under exactly that heat. A coated wok fails first at the spot you use most.

Scratch a nonstick pan and it is finished. Scratch carbon steel and you re-season it. A wipe of oil and some heat brings the surface back. A good one costs around sixty euros in the Netherlands. Basic versions start under twenty. Either way you buy it once.

The reckoning

Weekly cooking runs a wok hard. A coated pan gives you two to three years before the surface goes and the food starts sticking. You replace it, then replace it again.

Over twenty years the maths is not close.

Sixty euros against a hundred and twenty-six. Cook on it twice a week for twenty years and the wok costs about three cents a meal. It also holds a secondhand price on Marktplaats, where a well-seasoned pan sells quickly. A worn nonstick wok is worth nothing to anyone.

The patina

Every stir-fry lays down another micro-layer of polymerised oil. The pan turns from raw grey to deep black over the years. It gets more nonstick as it ages.

This is the patina dividend. The steel appreciates in use while the coated pan loses value from the first meal. A wok your parent seasoned can still be the best pan in your kitchen.

Verdict. Season it once and cook on it for the rest of your life.
