I agree with @YARNLADY traditionally women cook in the home. Men worked outside of the home, so chefs were men. The men who are chefs, probably did most of the cooking at home too.
Now that women are in the workplace more, they are chefs too. And, men are picking up the slack more with domestic chores amd might cook more often at home.
Probably women are still more likely to not work, or work part time, so the cooking falls on them more often.
I know a lot of men who do the cooking at home though. Funny, my ex, his dad never cooked, but all the sons cooked at least some of the time if not the majority of the time at home. They were a macho bunch of guys, disrespectful of women in many ways, all had mistresses, and other macho bullshit, but all were willing to do household chores. My ex, we were in high school, used to vacuum the house all the time, and cook, always kept his room clean, watched his neices when they visited, changed their diapers. His mom loved that he did all that stuff.
