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

What each ingredient does

Flour
Thickens the sauce as it cooks with the liquid, giving it body.
Sugar
Adds sweetness and helps give the sauce a smooth, rounded flavour.
Butter
Adds richness and a silky mouthfeel when stirred in off the heat.
Vanilla
Provides the main aroma and flavour of the sauce.

The step that matters

Boil the flour mixture for 5 minutes. Flour starch only thickens fully when heated in liquid long enough to swell and set. Boiling too briefly can leave the sauce thin or floury-tasting.

Swap the vanilla

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

  1. Raisinfits better
  2. Vanillathe original
  3. Figfits less well
  4. Coconutfits less well

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