Most people love cheese, whether in chunks or strips, or melted on bread for a grilled sandwich. It is a part of the cuisine of nearly every culture, and variations on the theme are legion. Cheese is usually categorized into four types: soft, semi-soft, semi-hard and hard.
Blue-veined cheeses are mostly made from cow's milk, except for a few standouts like Roquefort, which is made from sheep's milk. To achieve the blue marbling, various Penicilliums are sprinkled in powdered form into the milk or over the curds. The Penicillium types vary depending on the desired cheese.
