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

What each ingredient does

Corn starch
Thickens the liquid into a light, set custard-like base as it boils.
Egg whites
Whipped into a foam that forms the light, airy topping.
Oranges
Provide the fruit base and their fresh citrus flavor.
Lemons
Add acidity and brightness to the sweet syrup.

The step that matters

Boiling the corn starch mixture. Corn starch must boil long enough, while stirred constantly, to fully gelatinize and thicken; stopping early or letting it scorch leaves a thin or lumpy base.

Swap the lemon

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

  1. Figfits better
  2. Cherryfits better
  3. Blueberryfits better
  4. Lemonthe original

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