CAST IRON PANS.
Love em, learn to treat them right and they will treat you right.
When you first get a new pan, Treat with oil by letting it heat up in the pan for 10-15 mins, make sure the oil gets in all the knooks and crannies, then flush with cold water.
This seals the pan and adds flavour to the pan.
Just make sure to never use soap on it, just scrape off all debris, rinse off with hot water.
