Roquefort is a famous blue cheese from the south of France, specifically the region of Roquefort-sur-Soulzon. It is made from sheep's milk and is known for its distinct tangy flavor and creamy texture. The cheese is aged in natural caves, which contribute to its unique taste and the development of blue mold, specifically Penicillium roqueforti. This cheese has a protected designation of origin (PDO) status, meaning it can only be produced in certain areas of France using traditional methods. Roquefort is often enjoyed on its own, in salads, or paired with fruits and wines, making it a popular choice among cheese lovers worldwide.
