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

What each ingredient does

Egg
Thickens and binds the filling as it heats and sets.
Flour
Thickens the liquid into a smooth, spreadable filling as its starch swells.
Sugar
Adds sweetness and balances the sharpness of the vinegar.
Raisins
Add sweetness, chewy texture, and moisture to the filling.
Butter
Adds fat for richness and a smoother mouthfeel in the filling.
Vinegar
Adds acidity that brightens the sweetness of the filling.

The step that matters

Cook over medium heat, stirring constantly until thick. Flour and egg thicken as they heat, but they can clump or scramble if the heat is too high or the mixture is left unstirred. Constant stirring spreads the heat evenly so the filling thickens smoothly.

Swap the raisin

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

  1. Raisinthe original
  2. Vanillafits about as well
  3. Figfits less well
  4. Lemonfits less well

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