What is the white layer on Brie cheese?

The white layer on Brie cheese is called white mold. It's actually a type of edible mold called Penicillium candidum.

Here's why it's there and what it does:

* Flavor and Texture: This mold is intentionally added to Brie during the cheesemaking process. It contributes to the cheese's creamy texture and nutty, mushroomy flavor.

* Protection: The white mold forms a protective layer that helps to prevent other, unwanted molds from growing on the cheese.

* Ripening: The mold also plays a role in the cheese's ripening process. It breaks down the milk proteins and fats, creating the characteristic creamy texture and rich flavor.

Don't be afraid of the white mold! It's safe to eat and a vital part of what makes Brie cheese delicious.
