My oldest girl will never be a great cook because she's like her mother: it's always the same things she cooks. If her husband's or boyfriends didn't know how to cook, she would have starved trying to learn. Her husband does 90% of the cooking, and her boys are coming along, learning how to cook from him. Don't know if they'll grill in the wintertime, but that gene will kick in one day.
My younger daughter's ex is a good cook, but so is she. She's taught her girls well. I went to pick up the youngest Sunday, and she was fixing supper. The girl's only 10. She has a good start towards being a pastry chef. Her other sisters know their way around a kitchen, too.
