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

What each ingredient does

Butter
Forms the fat base that carries flavour and gives the sauce a rich mouthfeel.
Flour
Thickens the liquid into a smooth sauce as its starch swells when heated.
Milk
Provides the liquid base and creamy body of the sauce.
Egg yolks
Enrich and thicken the sauce when gently heated, adding richness and body.

The step that matters

Adding the egg yolks. Egg yolks thicken by setting with gentle heat. If the sauce is too hot when they go in, they can scramble and turn grainy, so add them slightly beaten and keep the heat low.

Swap the onion

How well each one fits the dish's main ingredients (butter, carrot, milk, flour, pepper, egg):

  1. Capsicumfits better
  2. Potatofits better
  3. Leekfits better
  4. Onionthe original

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