When I was nine years old, my older cousin introduced her Hungarian friend, a beautiful girl with deep eyes. She prepared a traditional Hungarian dinner for us that evening, including dessert.
The desert tasted like nothing I ever had before or since. I can hardly remember it, though. I can't even remember what it looked like... Maybe it looked like baklava?
As strange as it sounds, this is not a plea for help in identifying the dessert. Rather, I think it's kind of nice to have a one-off memory like that, knowing that I will never taste it again.
