This is an OLD thread but didn't want to start a new one....
Looking up on Mr Internet on whether cooking in cast iron adds iron to your diet has been a topic of a lot of discussion. Many internet posts say it does. I think if your CI is properly seasoned, it won't. Seasoning supposedly keeps the food away from the raw iron. OK, maybe trace amount of iron will seep through the seasoning. One of my cousins said her father (my uncle, of course) taught her that cooking in CI is definitely a source of iron for the blood. I respectfully disagree.
One of my worst disasters was corned beef, cabbage and red potatoes for St Patric's day in a CI DO. Cabbage turned dark and tasted metallic. I thought the DO had enough seasoning but I guess I was wrong. I splurged and bought a LeCreuset DO for future use and it has worked fine. Had to buy some plastic utensils to protect the enamel but that's OK. In the past, our family almost always cooked chili, spaghetti sauce and others in a CI DO without any discernible metallic taste. Or maybe I just didn't recognize it.
Any thoughts?
FWIW...I still cook 15 Bean soup, Gumbo, Red Beans & Rice in a regular CI DO. I have a dedicated CI pot for Jambalaya. I also cook mixed veggies (no tomatoes) in a CI skillet as well as refried beans (involves bacon). Scrambled eggs with onions, garlic and bell peppers are done in a CI skillet, my answer to losing a co-worker's wife's Friday burritos during Covid. Also cooked sliced par-boiled potato slices with some olive oil and seasoning in a CI skillet. All delicious.
Refried beans in CI are the trinity. Then added to a SS stock pot with the beans and chicken stock..
One more thing...
One-pot meal with meat, beans, etc, similar to chili but not chili is also great. Learned that from my sister being a Girl-Scout. And living on weekends on a boat with a 2 burner stove.
