Derox Green Cheese is uniquely green. It has a very creamy consistency and a bitter taste. It is made from derox milk. It has also been used by natives for a long time as it is cheese, made from a local species.
Why did they not use the milk of the Bræ Wooly Cow? Because deroxes are everywhere, that's it.
The cheese is considered a staple food and is quite expensive outside of Axolotlia.
