Jokes aside, apparently it’s not teflon on parchment paper. Even if it was, it’s not the teflon itself, it’s the manufacturing of it that is problematic in terms of PFAs. Apparently also high heat is sufficient to cause Teflon to degrade and PFAs to be released. It’s crazy that it is still being used in cookware at all. I switched over to cast iron and Asian-grocery store brand stainless cookware, though my new air fryer has teflon and I’m suffering from sunk-cost fallacy in relation to it.
