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

What each ingredient does

Sugar
Provides sweetness and body to the sauce.
Butter
Adds fat and richness, giving the sauce a smooth mouthfeel.
Flour
Thickens the sauce as it heats with the boiling water.
Vinegar or acid fruit juice
Adds acidity that sharpens the sweetness and balances the flavor.

The step that matters

Pouring in the boiling water. Flour needs heat and liquid to swell and thicken. Adding the water all at once and boiling it keeps the flour from clumping and lets the starch thicken the sauce evenly.

Swap the nutmeg

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

  1. Cinnamonfits better
  2. Jalapenofits better
  3. Tarragonfits about as well
  4. Nutmegthe original

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