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

What each ingredient does

Butter
Adds richness and a smooth, rounded mouthfeel to the sauce.
Sugar
Provides sweetness and body as it dissolves into the liquid.
Flour
Thickens the sauce as its starch swells in the hot liquid.

The step that matters

Cook over hot water, stirring until thickened. Gentle heat from the double boiler lets the flour starch swell evenly without scorching or lumping. Constant stirring keeps the sauce smooth while it thickens, and pushing the heat too high can cause the flour to clump or the bottom to burn.

Swap the vanilla

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

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

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