The science behind seasoning: how to keep your cast iron naturally non-stick

Every Indian kitchen holds a few timeless traditions that rarely find their way into written recipes. One such tradition is the art of caring for cookware. The smooth, dark surface of an old iron tawa or kadhai is not the result of chance but of careful seasoning. Seasoning is the process that transforms raw metal into a naturally non-stick, rust-resistant surface. It blends science with tradition, enhancing both the performance and longevity of the cookware while preserving the authentic flavours of every dish.

When oil meets heat on cast iron, a natural reaction occurs, the oil bonds with the surface, creating a protective layer that improves with every use. Over time, this layer strengthens, giving the cookware a smooth finish and improved cooking performance. Regular use and simple care, such as applying a thin coat of oil and heating evenly with everyday oils like sunflower or groundnut, help maintain this natural layer and ensure durability for years to come.

Proper maintenance is essential to preserving the seasoning. Avoid harsh detergents, dry the cookware thoroughly after washing, and apply a light coat of oil before storage. With consistent care, your Embassy Cast Iron Tawa will not only perform better but also develop a deep patina and distinctive character, becoming an enduring part of your kitchen and a trusted companion for generations.
