Why is bleu cheese not spelled

The name bleu cheese is a corruption of the French word "bleu", meaning "blue". The cheese is named after the blue-grey mould that forms on its rind and veins, which is produced by the fungus Penicillium roqueforti. The fungus is naturally present in the air and can also be found in other types of cheese, such as Gorgonzola and Stilton.

The word "bleu" is pronounced as "bluh" in French, so the correct spelling of bleu cheese is "blue cheese". The spelling "bleu cheese" is a common misspelling that is often used in the United States.
