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

What each ingredient does

Flour
Thickens the sauce as its starch swells and sets when heated in the liquid.
Melted butter
Adds fat for smooth body, rich flavour and a glossy mouthfeel.
Cider vinegar
Adds sharp acidity that brightens the sauce and balances the butter.
Chopped onion
Adds savoury aroma and background flavour to the sauce.

The step that matters

Boil until it thickens. Flour only thickens fully when the mixture reaches a boil, and the starch needs to cook through to lose its raw, pasty taste. Stopping early leaves the sauce thin and floury.

Swap the onion

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

  1. Shallotfits better
  2. Mustardfits better
  3. Cucumberfits better
  4. Onionthe original

Fit is the average pairing score against cider, vinegar, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
