Is it normal in your country/culture/social group not to have much experience cooking? I had a lot of second-hand experience by the time I was 18 from simply watching my parents or other adults, and sometimes being asked to help.

I have some pretty basic recipes I cook if I'm a bit tired from work, I can make them without really thinking (e.g. diced chicken + green beans & cream + pesto.) Fortunately, the nearest shop is about 2 minutes detour from my route home, so I can wander in and buy the things I'm missing.
