Ooo, I really love it when a fictional universe truly portrays the culture difference in physical objects. For example, grated jerky (because the meat is as hard as rock) and a candle made entirely of cheese.
Most of the time, stories portray universes as parallel to our own with very similar cultural practices. It makes it relatable but loses the charm of fantasy by making it ground. Probably why I'm not that big of a fan of Tolkien works.
But then you have stories like these that portray how the environment forms it's culture and not the other way around. People and tools are the way they are because of where they live. Dragon steaks are tough because everyone has fangs, cheese is a candle because you wanted it melted.
These kinds of world building make the best kinds of stories.
