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

What each ingredient does

Eggs
Yolks thicken the filling and whites form the meringue topping.
Corn starch
Thickens the lemon filling as it boils.
Lemons
Provide the sharp acidity and flavor of the filling.
Sugar
Sweetens the filling and helps the meringue brown.

The step that matters

Thicken the filling fully. Corn starch only thickens once it reaches a boil and holds it for a moment, so an underboiled filling stays runny and may not set when cooled.

Swap the lemon

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

  1. Vanillafits better
  2. Coconutfits about as well
  3. Raisinfits about as well
  4. Lemonthe original

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