The best way to cook with cast iron pots and pans involves preheating the pan, using appropriate oil, and maintaining a moderate heat. Always season your cast iron before first use and regularly thereafter to create a natural non-stick surface. Use wooden or silicone utensils to avoid scratching the surface. Start with lower heat and gradually increase it to prevent food from sticking. Always clean with warm water and a brush, avoiding soap as it can strip the seasoning. Dry thoroughly to prevent rusting and store with a thin layer of oil to maintain the seasoning.
