Noticed this on the shelves in a supermarket yesterday. (I was hunting for clotted cream, but that’s another story.) I can’t recall if I’ve known before that “quark” was also a kind of cheese.
I suspect that this might have potentially amusing physics joke uses in the future.
To further my education, I looked up quark cheese on Wikipedia. All very interesting.
And, no, since you ask: There was nothing in there about quark cheese being made of string cheese…
