This article on how we grow to like foods we once hated is an interesting read. Have seen that happen to me and others I grew up with. The unthinkable reversals have happened. I used to attribute it to something strange that goes on with our taste-buds as we age - makes us like things as older adults that we hated as kids.
It made sense when J says "I bet you would like it because I hate it. Adults seems to love the very things kids hate and the other way around". It seems to work that way quite often down to specific types of Halloween candy that J will have in her reject pile. Quite often I may find something that works for me. Similarly, J is not interested in the kind of chocolate I like. As she grows older, we seem to find more things in common when it comes to food.
