My Wok, got it in an Asian store many years ago, made of who knows what ( no coating, not cast iron), you can make all sorts of fried stuff in it.
One large stainless steel pot to boil things in. I also have cast iron skillets
I have more stuff of course, but those things are the ones I use most and can't do without.
I dislike anything with non stick coating on it. They are usually scratched up very shortly even if I am careful. And that includes those copper pans. I got a large and a small one while ago. The coating came off both of them
I cook on either wood stove or very hot propane outdoor stove, so my cookware pretty much needs to be indestructible
