I have a cast iron dutch oven. It has a self-basting lid, basically it has a grid of little cone shapes on the underside of the lid. The idea is that liquid condenses on underside of the lid and these little cones help the liquid drip back down onto the stuff that is cooking.
I noticed that the tips were a little rusted but I decided to cook a one pot chicken and rice dish in it any way. It the food safe to eat? I couldn't discern any type of rust flavor or anything in the food. I searched around on the web a bit and couldn't really get a straight answer about eating rust. All I've read is that you have to injest quite bit to be of any concern. I think that cooking and eating the food this one time probably won't put my health at risk.
Does anyone have a more definitive answer on this?
