As a technology, cast iron cookware has withstood the test of time -- it's just as welcome in the kitchen today as it was a hundred years ago.
This is not surprising. Cast iron conducts heat extremely well , is relatively inexpensive, and lasts forever.
The only drawback to cast iron is that it requires a little TLC. Once you understand the basics, you'll find that caring for cast iron is straightforward and easily incorporated into your everyday cooking routine. Here are the basics:
Use wood or plastic utensils to avoid scratching through the cast iron's seasoning.
Clean with hot water. Do NOT use soap. Soap lifts grease and the pot's seasoning.
For cleaning stubborn spots use a stiff scrub brush or non-metallic utensil. One option is to add water and return to a simmer.
Dry thoroughly and apply a light coat of vegetable oil. Wipe off any excess oil and store with the lid off or slightly off center for ventilation.
