I think a lot of it's cultural too. My mum was a no nonsense plain English cook. The nearest we got to a herb as kids was mint in the new potatoes and parsley with the fish. We also lived in a small village that just didn't have the likes of Indian or Chinese restaurants, as a result I was 22 before I first smelt curry, it made me vomit then and it makes me vomit now. I'm trying to be more adventurous and I do use a fair selection of herbs, but there are some things which I just can't get past and curry is one of them, I just don't understand how anyone can smell it and then voluntarily put it in their mouth, though I'm sure that if I'd been offered it as a kid I'd probably be able to eat it now without trouble.
