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 of the sauce that the thickener sets into.
Flour or arrowroot
Thickens the milk as it heats, giving the sauce body.
Butter
Adds fat and richness, giving the sauce a smooth, velvety mouthfeel.

The step that matters

Bring to a boil while stirring continuously. Starch in flour or arrowroot swells and thickens only when heated, and the milk can scorch on the bottom of the pan or form lumps if not stirred constantly.

Swap the mace

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

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

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