>Whereas for Zildians, "Jello" is one of those dead giveaways that tags someone as USn.

Here too.

"Jello brand" geletin dessert sounds 'sgusting! Like the paket of cake mix a friend brought over which proudly proclaimed "With real artificial flavor".

Although we know that some people hate lengthy discussion about food. ...
Part of the growing up process (if we are lucky) is that the things we learn in our childhood are not necessarily the only answer. I can learn to live with the idea that people are not wrong when they write "aging", rather than "ageing" but food beliefs, because they relate to sensation, not thinking, are harder to change. Perhaps it is so important that we don't eat food that is poisonous, we are programmed to accept what we are told by our own culture. The window of opportunity for new tastes is relatively small. While as an adult we may learn that anchovies and olives taste better than we may have remembered as a child, the tastes of childhood (eg peanut butter and jelly) are harder to re-programme. In fact some smells, literally turn our stomach, I still can't drink gin, having come across it as a child and hated the smell.
