As a kitchen professional, you understand the value that cast iron cookware brings to your culinary arsenal. Its durability, heat retention, and natural non-stick properties make it a staple in many professional kitchens. However, one recurring issue that chefs and cooks face is cast iron seasoning flaking after induction use. This can be an unexpected hurdle, especially when using modern induction cooktops, which are increasingly popular in professional settings. Understanding why this flaking occurs and how to address it is crucial for maintaining the performance and longevity of your cast iron pans.
Understanding Cast Iron Seasoning
Before diving into the specific issue of seasoning flaking, it's important to grasp what seasoning is. Seasoning is a layer of polymerized oil that is baked onto the surface of the cast iron. This layer not only provides the pan with its non-stick properties but also protects it from rust. Proper seasoning is essential for the performance of cast iron cookware, and maintaining this layer requires regular attention and care.

Why Does Seasoning Flake?
Seasoning flaking can occur due to several reasons, especially after induction cooking. The rapid changes in temperature and the precise heat distribution of induction cooktops can stress the seasoned layer. This stress can cause the layer to crack or flake off in areas, particularly if the seasoning was not applied evenly or if the pan was not properly preheated. The interaction between the induction heat and the oil layer is different than with traditional gas or electric stoves, which can exacerbate this issue.

Preventing Seasoning Flake
Preheat Properly
Proper preheating is essential when using cast iron on an induction cooktop. Make sure your pan is gradually brought up to temperature to prevent thermal shock, which can cause the seasoning to crack. For tips on preheating techniques, check out this preheating guide.
Maintain Your Seasoning
Regular maintenance of your cast iron's seasoning is crucial. After each use, clean the pan with hot water and a soft brush, avoiding harsh soaps or scouring pads that can damage the seasoning. Apply a thin layer of oil after cleaning and heat the pan until the oil begins to smoke. This will help reinforce the seasoning layer.
Choose the Right Oil
Not all oils are created equal when it comes to seasoning. High smoke point oils such as flaxseed, canola, or grapeseed are recommended for seasoning cast iron. These oils polymerize well and create a durable layer of seasoning.
Troubleshooting Flaking Issues
If you notice your seasoning is flaking, it may be time to strip and reseason your pan. This involves removing the old seasoning with a mild abrasive and reapplying a fresh coat of oil. This process can restore your pan to its optimal condition and is a valuable skill for any kitchen professional.
