It doesn't seem like he was fired, so he's still an engineer by day... she's just trying to cheer him up by mentioning his cooking, as he's a hobby chef that can cook her panties off by night...

His cooking is purely science. It has great nutritional balance but severely lack in taste lolz.
I think he just learned the joy of yum food from his wife but when he cooks, it's always the science-style nabe.
