Hello, I'm trying to avoid any non-stick frying pans but I'm confused about the best options to go for - stainless sounds like the best but a pain to cook with (anyone with experience?), then there's carbon steel and cast iron but you can't really cook acidic sauces in them. Would love to hear from people with these types of frying pans especially stainless steel. I have stainless steels pots which I love.
