Are there foods that I shouldn't cook in Cast Iron?
Foods which are very acidic (i.e. beans, tomatoes, citrus juices, etc.) should not be cooked in Seasoned Cast Iron until the cookware is highly seasoned. The high acidity of these foods will strip the seasoning and result in discoloration and metallic tasting food. Wait until cast iron is better seasoned to cook these types of foods.
Lodge Enameled Cast Iron is not affected by acidity and can be used with all foods.
