I apologize for YET ANOTHER cast iron related question..
My cast iron was (or i thought it was) well seasoned, and the other day, I made burger. Just plain ol' burgers (with salt and pepper). I put some olive oil in the pan, and let it get screamin' hot, and slapped the burgers in there.
After cooking them, there are two, brown circles in the pan (where the burgers were cooking.)
Do I scrape off these brown bits? If so, with what? Or do I just rub some more canola oil in it and call it a day?
This is generally the problem I have with cast iron - I have no idea what I'm supposed to do to it after I'm done cooking food in it (Like bacon, or hamburgers.)
So, what do you do after you cook food in your cast iron, and you have residue? Wash with soap and water, or coarse salt and a rag?
Also (sorry, I know this is getting long) wouldn't using bacon grease to season the pan be a BAD idea, because the bacon fat could go rancid, right?
