When we were little my Dad and older brothers showed us how to cook ( my mother can cook but hates it)- we started with raw food, how to make a salad, fruit and cream desserts etc, moved onto 'all-in' things like stew, soups, chilli con carne, paella, curries, chicken in white wine sauce, as well as how to cook accompaniments ( rice, pasta, spuds, chips, wedges, etc) and then individual things like roasts, cakes, pastries etc and more importantly how to follow recipes. I can now cook more or less anything but only because I was shown how. All of the above took a very short time to learn ( the rest was trial and error practice). I don't know what cookery involves at school ( never went to school) but I would have thought there ought to be at schools somewhere a 'common sense class' where people are taught how to cook, how mend things, how to change a a lightbulb, how to grow things, how to write a letter, how to complain and how to just equip yourself for life. If people are leaving school without knowing how to peel a potato something is very wrong imho.
