True.
But non-stick should work as adverted.
Some non-stick pans burn butter too easily for some reason.
Most people think ads for metal bakeware will deliver as proposed.
I’m here to tell you what I learned from my dear departed mum: Low heat. If you have to cook something over a fire (electric or gas) keep the heat low. The butter/margarine or lard/shortening/oil does a better job at low heat. If the heat is high enough to smoke, it WAY TOO high.
Cooking with coconut oil is better for you, but because it smokes at medium heat, whatever you cook in it will be healthier because you won’t cook the essential nutrients out of it.
