noun [mass noun]
A soft, salty, strongly flavoured white cheese with blue veins.Pregnant women were told to avoid paté and soft-ripened cheeses (Brie, Camembert, Danish blue, Gorgonzola and Stilton)....
- Deciding to go for a niche market and make a blue cheese, they tried to replicate the sort of cheeses that were then being imported into Ireland, such as Stilton or Danish blue.
- The mould itself, which grows naturally in the cave and can be cultured on pieces of bread, is used elsewhere, e.g. in the production of Danish blue.
