What is the green stuff in stilton?

The green stuff in Stilton cheese is actually blue mold, specifically Penicillium Roqueforti.

* This mold is carefully introduced during the cheesemaking process.

* It's what gives Stilton its characteristic sharp, pungent flavor and its blue-green veins.

* The mold develops as the cheese ages, and it breaks down the fats and proteins in the cheese, creating those distinct flavors and textures.

So, while it looks green, it's actually blue mold that makes Stilton so special!
