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

What each ingredient does

Cornstarch or flour
Thickens the liquid into a smooth sauce as it heats and starch swells.
Sugar
Adds sweetness and body to the sauce.
Vinegar
Adds a touch of acidity that brightens the sweetness.
Butter
Adds richness and a glossy mouthfeel to the finished sauce.

The step that matters

Stirring in the starch paste before heating. Starch must be fully dispersed in cold liquid first; if it is dropped in hot or unstirred, it clumps and the sauce turns lumpy instead of smooth and thick.

Swap the vanilla

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

  1. Raisinfits about as well
  2. Vanillathe original
  3. Figfits less well
  4. Lemonfits less well

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