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 the thickened sauce is built on.
Cornstarch
Thickens the milk into a smooth, pourable sauce as it heats.
Butter
Adds fat for richness and a smooth, silky mouthfeel.
Raw egg
Sets gently with the warm sauce, adding body and richness.
Lemon juice
Adds acidity that brightens the rich, creamy sauce.

The step that matters

Adding the beaten egg off the heat. Egg proteins set at about 70°C and can scramble if added to a boiling sauce. Removing the pan from the heat first and stirring well lets the egg thicken the sauce smoothly.

Swap the mace

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

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

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