The Science Behind Blue Cheese
Blue cheese is characterized by the presence of Penicillium roqueforti, a mold that gives the cheese its distinctive blue-green veins. This mold is safe to consume and contributes to the cheese’s unique flavor and aroma. However, it is also highly perishable, making it susceptible to spoilage when exposed to warm temperatures.
