How can I tell my wife she doesn’t know how to cook without getting in trouble? Or do I just take the anger?

I noticed my wife making a bunch of random mistakes as if she’s never cooked in her life. If she looks at a recipe she can get through it but isn’t the best when it comes to avoiding cross contamination or that kind of issue

I just saw her cook eggs in a stainless steel pan. However….she takes the pan out of the cabinet…puts cold butter in it…breaks two eggs in it…then puts the pan on the stove. I’m completely shocked that someone would do that.

Are there classes that would help her? Or maybe even cooking school?
