Last week I cooked breakfast at my MIL's home. The skillet used for frying eggs is a non-stick skillet. A very old non-stick pan at that. Its surface was compromised with flaking and scratches. I was so hungry and went ahead and used it. All the while dreaming of my cast iron skillets back home (sigh;( There are so many controversies about using non-stick pans that I ditched my old ones a few years ago and replaced them with a nice set of non-coated-stainless-steel ones. These are in addition to my (3) cast iron skillets, griddle, grill pan and Dutch oven. When properly seasoned, they are non-stick. Some studies report that using cast iron for cooking can help impart iron to your diet.
