Soft blue cheese is a creamy cheese where blue cheese mold is added to the curds during the cheesemaking process. The mold is allowed to grow in veins and spots within the cheese wheel, producing the sharp, pungent, earthy flavors that are the hallmark of blue cheese.
A soft or creamy blue cheese can be made by adding cream to the curd as the cheese is made. Soft blue cheese is typically a younger cheese that is not aged for long. In contrast, a crumbly blue cheese is aged for a longer period of time to reduce the moisture content and create a denser, more crumbly curd. A blue cheese crumble can be sprinkled easily atop burgers, pasta, and salads to add a sharp, rich flavor.
