Cast Iron Cookware. I have a cast iron skillet and a dutch oven. My boyfriend is an absolute dumplin' and always does the dishes after I cook, and has managed to remove the seasoning from them both. They are now looking so naked that I avert my eyes...How do I re-season them? Honestly, the boyfriend's from Mississippi, and I really assumed that southerners just knew how to care for these things. Bless his heart!
