I recommend everybody has SOME teflon.
Cooking oil might be in short supply. And you can clean teflon with the barest minimum amount of water. (not to mention soap!)
I have been using the same cast iron skillet for over thirty years. It’s seasoned to the point it’s better than teflon.
(And no dubious chemicals soaking into the food that way, which is what I hear happens when you cook on teflon.)
Anyone can buy cast iron skillets and dutch ovens at Wal-Mart, they carry the Lodge brand, which is made in the USA.
May I butt in here on teflon pans?
I would not use them on a campfire or other uneven heat, at last, what we knew 30 years ago, is in the news.
The gases released from teflon pans will make you sick, maybe even kill you.
People were having healthy parrots die, back in the 1970’s and it was from getting the teflon pans too hot, the gas killed the birds, it was in the bird books/magazines.
If one is short on water, then on a regular pan, not teflon, one can use a handful of tough grass and sharp sand to clean the pans.
