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

What each ingredient does

Egg whites
Whipped into a stiff foam that forms the light, airy meringue topping.
Cornstarch
Thickens the cooked lemon mixture into a clear, sliceable jelly.
Sugar
Sweetens the filling and helps stabilize the whipped egg whites.
Lemon juice
Adds acidity and sharp lemon tartness to balance the sweetness.
Bread crumbs
Absorb liquid and give the filling body.

The step that matters

Cooking the lemon jelly until clear and thick. Cornstarch only thickens fully once the mixture reaches a simmer and is held there briefly. Undercooked starch stays runny and can make the filling weep or slump when cut.

Swap the lemon

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

  1. Vanillafits better
  2. Figfits better
  3. Datesfits about as well
  4. Lemonthe original

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