Bold, pungent cheese with blue-green mold veins. Used in dressings, sauces, and as a finishing cheese.
Substitutes
Feta — 1:1. Feta shares the salty, tangy crumble. Milder without the mold sharpness. Good in salads and dressings.
Parmesan Cheese — 3/4 cup parmesan per 1 cup blue cheese. Parmesan provides similar umami saltiness. Grate finely. Lacks the funky tang of blue mold.
Gouda — 1:1. Smoked gouda offers bold flavor without the funk. Very different profile but satisfies the 'strong cheese' role.
Cream Cheese — 1:1 (add pinch of salt and dash of vinegar). Cream cheese is much milder but works in dips and dressings when blue cheese intensity is unwanted.
