Cast Iron vs Carbon Steel Kadai: Which One Is Right for Your Kitchen This Festive Season?

Dear reader,

Festive season is round the corner, and if there is one vessel that works overtime in an Indian kitchen through Navratri and Diwali, it is the kadai. Deep-frying poori, samosas, chaklis and jalebis, or slow-cooking a big pot of curry for a house full of guests — the kadai does it all. At Trilonium, we make kadais in both cast iron and carbon steel, and we get asked often: which one should I actually buy? Here is an honest answer.

Why the Kadai Earns Its Keep at Festival Time

Unlike a tawa or a skillet, a kadai is built for volume and for oil — it needs to hold heat steadily through a long frying session, not just for one or two pieces but for the whole batch. That is where the metal you choose starts to matter.

Cast Iron Kadai: Built for Heavy, Slow Frying

Our cast iron kadais — the CrockWok range — are noticeably heavier than their carbon steel cousins. A 30cm CrockWok kadhai, for instance, weighs about 3.7 kgs, against roughly 1.2 kgs for a carbon steel wok of the same size — nearly three times lighter for an equivalent size. That extra mass in the cast iron is not a drawback, it is the point: it holds and releases heat slowly and evenly, which is exactly what you want when you are frying jalebis in batches or letting a kadai curry simmer on a low flame for a long time without scorching.

Carbon Steel Wok: Lighter, Quicker to Heat Up

Our carbon steel Chinese woks are considerably lighter, which makes them easier to lift, tilt and toss — handy if you are stir-frying or making quick starters. They are also made to double up as a kadai for deep-frying and cooking curries, not only for wok-tossed dishes. If your kitchen sees a lot of quick, high-flame cooking and you would rather not lift a heavier pan every time, this is worth considering.

What Both Have in Common: TilCrust™ Triple Seasoning

Whichever metal you pick, every piece of Trilonium ferrous cookware — cast iron or carbon steel — comes triple-seasoned with TilCrust™, our proprietary blend of cold-pressed vegetable oils, cured onto the surface three times before it reaches you. There is no synthetic non-stick coating on either — just a natural, oil-based seasoning that only gets better with regular use.

Caring for Your Kadai After a Frying Marathon

Deep-frying is hard on any seasoning — hot oil, repeated use and the occasional scrub afterwards can wear the TilCrust™ layer thin over time. This is normal and not a defect; it simply needs to be rebuilt now and then. A quick rub with our TilCrust™ BeesWax Seasoning Tikki after a heavy cooking day, followed by a light warming on the stove, helps restore the surface and keep it performing the way it should through the festive season and beyond.

So, Which One Should You Pick?

If your festive cooking involves long, slow deep-frying in bulk — think jalebi, gujiya, or a big batch of pooris — go with a cast iron kadai for the heat retention. If you want something lighter for quicker, everyday cooking that can still double up as a kadai when needed, a carbon steel wok is the practical choice. Either way, you are cooking in solid iron or steel, with nothing synthetic between your food and the pan.
