Are roquefort cheese and blue the same?

Here's the breakdown:

* Roquefort cheese is a specific type of blue cheese. It is made from sheep's milk and aged in caves in the Roquefort-sur-Soulzon region of France. It has a very distinctive, strong, and pungent flavor.

* Blue cheese is a broader category of cheese that includes Roquefort, Gorgonzola, Stilton, and many others. All blue cheeses have blue-green veins running through them, caused by the mold *Penicillium roqueforti*. This mold gives blue cheeses their characteristic pungent flavor and aroma.

In short:

* All Roquefort cheese is blue cheese, but not all blue cheese is Roquefort.

Think of it like this:

* Roquefort is like a specific brand of soda, like Coca-Cola.

* Blue cheese is like the larger category of "cola".
