Cast iron wins. A cast iron tawa holds heat for crisp, golden dosas, takes high heat and metal spoons, and lasts for years. A non-stick tawa depends on a coating that wears out, cannot take much heat and has to be replaced. Here is the side-by-side.
The side-by-side
| What matters | Cast iron | Non-stick | Winner |
|---|---|---|---|
| Crisp edges | Browns evenly and crisps the edges | Thin pans lose heat when the batter hits, so dosas can turn out pale | ✓ Cast iron |
| Heat holding | Stays hot, dosa after dosa | Heat drops quickly on thin pans | ✓ Cast iron |
| High heat | Made for it | The coating is not meant for very high heat | ✓ Cast iron |
| Metal spoons | Kroslo's is listed as metal-spoon friendly | Metal scratches the coating | ✓ Cast iron |
| Lifespan | Built to last years | The coating wears with use | ✓ Cast iron |
| The surface | Kroslo's has no polymer coating | The non-stick layer is a coating, and when it goes, the non-stick goes with it | ✓ Cast iron |
| Replacing it | Buy once | Replace it when the coating wears or scratches | ✓ Cast iron |
| One pan for more | Dosa, roti, chilla, uttapam | Fine for dosa, but heat limits what else you can do | ✓ Cast iron |
Crisp, golden dosa
A good dosa needs a pan that stays hot when cold batter lands on it. Cast iron does exactly that, so the base sets fast and the edges go golden and crisp. Many non-stick tawas are thin, lose heat the moment the batter hits, and give you a softer, paler dosa.
Heat is where non-stick gives up
Non-stick coatings are made for low to medium heat. Very high heat can damage them, and overheating an empty pan is a common way they get ruined. Indian cooking is not low heat. Cast iron is built for it, so you can heat the tawa properly and cook the way you want to.
Metal spoons and scrubbing
With a non-stick pan, you have to think about every utensil. One metal spatula can scratch the surface for good. Kroslo's cast iron is listed as metal-spoon friendly, so you can flip, scrape and serve without worry.
The coating is the weak point
A non-stick tawa is only as good as its coating. Once it is scratched or worn, the pan stops doing what you bought it for. Safety guidance is to stop using a badly scratched or peeling pan, which means replacing it. Kroslo's pans have no polymer coating, so there is nothing to wear off, peel or scratch away.
Buy once
A non-stick tawa is a pan you will replace. A cast iron tawa is a pan you keep. Kroslo's Dosa Tawa comes with a 5-year limited warranty.
The one thing non-stick does well, and how to beat it
Non-stick forgives a cold pan. Cast iron asks for a minute or two of preheating, no more. Heat the tawa on medium, sprinkle a few drops of water, and wait for them to sizzle and vanish. Then oil it lightly, pour and spread.
Which should you choose?
If you make dosa, roti or chilla and want crisp results and a pan that lasts, choose cast iron. Kroslo's Dosa Tawa comes in 26, 28 and 30 cm and works on gas and induction. See how to choose the best cast iron tawa for dosa.
