Unlike other cast iron skillets, the Le Creuset square Skillet Grill does not require seasoning, due to Le Creuset's durable Satin Black enamel finish. Le Creuset's exterior is long lasting and resists chipping. The cooking surface is impermeable and is also ideal for marinating foods with acidic ingredients such as lemon juice or wine. The Le Creuset square Skillet Grill can be safely preheated to a hot surface temperature for caramelization and searing. The Satin Black enamel surface is also ideal for dry cooking. Made in France.
