What is cast iron?
Cast iron is iron poured into a mould and allowed to set — which is why a cast iron pan is a single, thick, solid piece with no coating bonded on top. That thickness is the whole point: it takes a while to warm up, and then it stays warm.
Why it cooks differently
Thin pans lose heat the moment food touches them. A preheated cast iron pan carries enough stored heat to keep going — so a dosa crisps instead of steaming, and a paratha browns instead of drying out. It also means you cook on lower flame than you might expect.
Seasoning, simply
Seasoning is a thin layer of oil that has been heated onto the iron until it hardens into a smooth, dark surface. It is not a coating applied in a factory and it is not permanent — it builds up through cooking and care, and it can be repaired at home if it wears back.

| Heats up | Slowly | Quickly | Quickly |
| Surface | Seasoning built by use | Applied coating that wears | Bare metal |
| Care | Dry and oil after washing | Avoid scratching | Low maintenance |
Common myths
“You can never use soap.”
A little mild soap is fine. Leaving the pan wet is the real problem.
“It is too heavy to use daily.”
Weight varies. Our lightest tawa is 1.5 kg — choose the size that suits your hands and your stove.
“Rust means the pan is finished.”
Surface rust can be scrubbed off, dried and re-oiled. Cast iron is repairable in a way coated pans are not.
How to get started
Pick the one thing you cook most — dosa, roti, curry — and start with that piece. One pan used often teaches you more than three used occasionally.
