My niece just called and asked if I had ever had my food turn black when I was cooking in my cast iron cookware. She has seasoned it like she is supposed to but her food is still turning black. Anyone ever had a problem with this?
Yeah it is really cast iron. I told her that she may not her gotten it seasoned adequately..I’ve also heard that if you boil water in it that can happen.

Well either the fire is up to high or black specks are coming off. Ive done both.

I cook in cast iron all the time. I’ve never had that happen. That doesn’t sound right. Are you sure it’s really cast iron and not some sort of coated pan? I’ve had Teflon type stuff come off. It weirded me out since that stuff cannot be good for humans to ingest.
