Why Low Smoke Point Oils Ruin Your Cast Iron Seasoning
Repeating this process three to five times builds a robust foundation that will improve with every subsequent use. This is distinct from simply heating oil in a pan; successful seasoning demands precise temperature control and sufficient time for the molecules to align and harden evenly across the surface.
Rice Bran Oil: Exceptionally high smoke point and thin consistency allow for even penetration. When an oil with the correct molecular structure is heated to the right temperature, it cures into a durable coating.
