I think you're right Di, time was whether you enjoyed it or not you had to be able to prepare and cook. I don't often enjoy cooking - although I go through phases when I do enjoy it - but I can cook and am self-taught aside from the basics I learned at school, as my mum lacked both skill and the patience to teach me - she couldn't stand anyone under her feet in the kitchen
I learned to cook cakes and bread when I was a skint single mum, when I was younger and first married I had a Good Housekeeping book as a wedding present and that was a godsend. I even used to throw dinner parties for my first husband when he had his own business and needed to schmooze clients - home made pate, boeuf bourgignon, pavlova etc etc Hence the Abigails Party frocks etc
These days if I was starting out I suspect I wouldn't have learned any of those skills - it would have been all prepared carrots and M&S ready to pop in the oven
