Cheese ripening the cheese by fungi to occur. Mould-ripened cheeses ripen faster than hard cheeses, in weeks as opposed to the typical months or even years. This is because the fungi used are more biochemically active than the starter bacteria. Where the ripening occurs is largely dependent on the type of cheese: some cheeses are surface-ripened by moulds, such as Camembert and Brie; and some are ripened internally, such as Stilton. Surface ripening of some cheeses, such as Saint-Nectaire cheese, may also be influenced by yeasts which contribute flavour and coat texture. Others are allowed by the cheesemaker to develop bacterial surface
Cheese soup in chunks or pieces. Cheeses used include hard cheeses like Cheddar, Gruyère and Parmesan cheese and soft ones such as farmer cheese, Gouda cheese, muenster cheese, queso blanco and queso Chihuahua. The cheese adds both flavor and nutritional value to the soup. Processed cheese (including Velveeta), such as pasteurized process cheese and pasteurized process cheese food is sometimes used instead of natural cheese. Some cheese soups have a rich flavor and may be high in fat due to the use of high-fat ingredients such as butter and heavy cream, in addition to the fat in the cheese. Fat content of
