Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Flour
Starch thickens the hot water into a smooth, pourable sauce body.
Butter
Fat adds richness and a silky mouthfeel to the sauce.
Tasty cheese
Melts into the sauce to add savoury, cheesy flavour and body.
Lemon juice
Acidity brightens the flavour and balances the richness of butter and cheese.

The step that matters

Cool before adding the lemon juice and cheese. Cheese proteins and fat can turn grainy, oily or stringy when added to very hot liquid, and acid can curdle dairy. Letting the sauce cool slightly helps the cheese melt smoothly and stay emulsified.

Swap the white pepper

How well each one fits the dish's main ingredients (flour, butter, lemon, cheese):

  1. Thymefits better
  2. Parsleyfits better
  3. Capersfits better
