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

What each ingredient does

Milk
Forms the liquid base that thickens into the sauce.
Butter
Provides fat and richness, and combines with flour to form the roux.
Flour
Thickens the sauce by absorbing liquid as its starch swells when heated.
Cream
Adds richness and a smoother, silkier texture to the finished sauce.

The step that matters

Stirring the milk into the butter and flour. Adding liquid gradually while stirring keeps the roux smooth and lumps out of the sauce, and constant stirring prevents the milk from scorching on the bottom of the pan.

Swap the mace

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

  1. Nutmegfits better
  2. Parsleyfits better
  3. Thymefits better
  4. Macethe original

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