I can and cook well - and so does my dh. We will do anyting from making a stock to every day meals, to full blown gourmet dinner parties.
But I am 44 - and it does appear that younger people (and by that, I mean men as well as women) are losing the necessary skills.
I remember being shocked by a girl in the office about 7 years ago saying that she really did need Delia to go through the basics of how to cook an egg, as all she knew how to do was to read the insturctions on the back of a ready made meal and put it in the oven. . She would have been in her late 20s I reckon, and was not an unintelligent woman.
Interestingly, I learnt to cook via baking, as my mum was a working mum and din't have time to do every day cooking with me - but we did bake together at weekends. So I can follow recipes brilliantly (and cakes, pastries amd meringues are all easy as far as I am concerned) but it has taken me time to learn how to cook "instincitively" and to learn cuts of meat etc.
Whereas dh learnt to cook soups etc with his mum (also a working mother - but with 5 kids so they all mucked in) and worked in a butcher to help his BIL when he was at school, so was much more comfortable with throwing things together (although I have now caught him up on that! )
