Cooking with seasoned cast iron pans is a common practice, and in general, putting water on the stovetop while using a seasoned cast iron pan should not cause any damage to the pan itself. Cast iron pans are quite durable and can handle exposure to water without significant issues.
However, there are a few things to keep in mind:
Rust Prevention: While a seasoned cast iron pan is relatively resistant to water, leaving water in the pan for extended periods can lead to rust formation. After cooking with water, it's essential to dry the pan thoroughly and promptly. Also, consider lightly oiling the pan after drying to maintain the seasoning and prevent rust.
Sudden Temperature Changes: Drastic temperature changes can potentially cause thermal shock and crack the cast iron. Avoid pouring cold water into a hot cast iron pan as this can lead to damage. Similarly, avoid placing a hot cast iron pan under cold running water or in a sink filled with cold water.
Maintenance: Regular maintenance and re-seasoning of the cast iron pan are essential to keep it in top condition. If you notice any rust or loss of seasoning, it's a good idea to re-season the pan to restore its non-stick properties and protect it from damage.
Stove Material: Ensure that your stovetop is suitable for using cast iron cookware. Some glass or ceramic cooktops may have specific restrictions on using heavy cast iron pans, so it's essential to check your stove's user manual for guidance.
In summary, using water while cooking with seasoned cast iron pans should not be a problem as long as you take proper care and follow the guidelines mentioned above. Cast iron cookware can be fantastic for various cooking tasks and can last a lifetime with the right care and maintenance.
