Decide how you’re using the cheese: crumble (salads, cheese boards) vs. stir-melt (sauces, pasta, burgers).
Start with a 1:1 amount, then adjust intensity: add a little more blue cheese if flavor is muted or add creamier base if it’s too sharp.
For crumbly substitutions (Roquefort, Wensleydale blue, Maytag blue), crumble finer than you think so it blends into sauces.
For softer substitutions (Gorgonzola dolce, cream cheese blends), warm gently or stir off-heat to avoid graininess.
Taste at the end and rebalance: a pinch of salt and a tiny squeeze of lemon can sharpen, while a spoon of butter/cream smooths.
