Ingredient

Blue cheese

Cheese veined with Penicillium, which breaks down fat into the sharp, peppery compounds that give it its bite. The styles differ more than the name suggests — Gorgonzola dolce is a spreadable cream, Roquefort is salt and sheep, Stilton sits between.

Sourcing
Cheese counter. Which blue a recipe wants usually matters: a dressing wants something salty and crumbly, a sauce wants something that melts.
Varieties
Roquefort, Gorgonzola, Stilton, Danish blue, Cashel Blue
Quality cues
Veining evenly spread rather than pooled, and a clean sharp smell. Ammonia means it is past its best.
Substitutions
Feta, for saltiness without the blue, Gorgonzola for Roquefort and vice versa
Storage
Wrap in waxed paper, not cling film — it needs to breathe, and plastic turns the rind slimy.
Shelf life
3-4 weeks refrigerated
