Onion goo

You know how sometimes you go somewhere new, and unexpectedly you end up eating something that blows your mind?  And then you spend months, even years, coming back to that memory, in odd moments, in the shower or on the bus?  And then you think, "God, I have to go on a desperate search for this thing RIGHT. NOW." but you can't find it anywhere?  And then you start wondering if it'd even be as good as you remembered, because time and memory have a tendency to drop rose-tinted veils over your senses?  And so this mythical dish lives on in your mind, floating in and out of your consciousness, causing moments of wistfulness for years on end?

Yeah.

This is the story of Zoe and the "onion goo."  Spoiler alert: it has a happy ending.
