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

What each ingredient does

Corn starch
Thickens the lemon liquid into a stable, sliceable body when cooked.
Egg whites
Whipped into the mixture to add lightness and a foamy, snowy texture.
Sugar
Sweetens the dessert and helps give it a smooth, set texture.
Lemon juice
Adds tart acidity that balances the sweetness of the dessert.

The step that matters

Beating the mixture while partly cooled. Beating while the mixture is still warm but no longer hot lets the whites fold in and form a light foam; if it is too hot the egg whites can cook and deflate, and if it is too cold the mixture will not whip up well.

Swap the lemon

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

  2. Coconutfits about as well
  3. Raisinfits about as well
  4. Lemonthe original

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