I have pointed it out over the years for a few times in the comments of various manga, but the majority of competition awarded chefs in the world are actually men. While it's true the statistics would be skewed due to it usually being easier for men to be more career oriented (men don't even get pregnant) and in the past it was more socially acceptable for men to be audaciously ambitious, at least the latter isn't anymore holding women back. Nevertheless, the point is that good cooking skills have absolutely nothing to do with a person's gender and thus whether the person is the wife or husband. Wives might cook a whole lot more meals in the world, but husbands can get just as good at it.
