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

What each ingredient does

Sugar
Adds sweetness and body to the filling as it dissolves in the liquid.
Cornstarch
Thickens the juice mixture into a smooth, sliceable filling when heated.
Egg
Listed in the ingredients but not used in any step, so its role here is not stated.
Butter
Adds richness and a silky mouthfeel when stirred into the hot filling.
Orange juice
Provides the main citrus flavour and liquid that the starch thickens.

The step that matters

Stirring while the filling thickens. Cornstarch can scorch on the bottom of the pan and form lumps if it is not stirred constantly over heat. Constant stirring keeps the starch dispersed so it thickens evenly.

Swap the orange

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

  1. Vanillafits about as well
  2. Orangethe original
  3. Raspberryfits about as well
  4. Figfits about as well

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