Blue vein cheese is the favorite for many cheese lovers. It is often the highlight of a cheese board, but also in savory dishes, sauces and dressings. Blue vein cheese, also known as blue mold cheese, is characterized by the blue mold. This is added as a powder or liquid to the curd and works under the influence of oxygen. During growth, blue fungi produce certain by-products, which provide the typical smell and taste. Some well-known blue cheeses are Blue Stilton, Huntsman and Shropshire Blue.
