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 balance the sharpness of the acid.
Butter
Adds fat for richness and a smooth, mellow mouthfeel.
Flour
Starch that thickens the sauce as it heats in the boiling water.
Vinegar or acid fruit juice
Adds acidity that brightens the sauce and cuts through its sweetness.

The step that matters

Pouring in the boiling water. Flour must be fully mixed into the sugar and butter before the liquid goes in, or it forms lumps. Boiling lets the flour starch swell and 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.
