1. Explainer: Cast Iron vs Stainless Steel – What’s the Difference?
Before diving into the comparison, let’s understand what each material actually is.
Cast Iron Cookware: Made from molten iron poured into a mold. It is heavy, retains heat exceptionally well, and develops a natural non‑stick surface when seasoned. It has been used for centuries and is prized for its durability and heat retention.
Stainless Steel Cookware: Made from a durable alloy of iron, chromium, and nickel. It has no coating – the cooking surface is bare metal. It is prized for its durability, non‑reactivity, and professional performance.
Key Difference: Cast iron is heavy with superior heat retention; stainless steel is lighter, more responsive, and requires proper technique to prevent sticking.
