Yes, teamwork in a marriage. One of my sisters (47 yrs.) has been a stay at home mom full-time for last 15 years of their marriage or so. They have been married 25 years with 2 adult children in their early 20's.

Her hubby has always cooked, shared housework etc. with his wife ever since I knew him..even before they married.

I suspect for brothers-in-law and for my partner, their mothers cooked most of their meals when they were growing up. There wasn't much "teaching" of recipes/cooking techniques to each boy. However I am aware my partner's mother did cook and bake in a style that her 2 boys loved to sit around and watch their mother cook and explain certain things along the way. Like little bits of storytelling..and shortly thereafter they knew why their mother's cooking and baking is excellent quality.

ANd this has transferred what they choose to stock the kitchen shelves, types of dishes they make and what they order /not order in restaurants. Imitation is the best form of flattery.
