I have plenty of friends who couldn’t cook before marriage and now cook gourmet meals, but they all admit that it was difficult for them during the first few months. Why add that to the stress of being newly married??
Coddling your girls and not teaching them cooking is easy in the short run, but causes problems in the long term. I personally think that a mother has a responsibility to teach her daughters cooking (and sons, but to a lesser degree) before marriage. My mother made sure we could all cook Shabbos by 12 for girls and 13 for boys. And yes, my husband definitely tasted some of my food before we got engaged, although I doubt it affected his decision.
