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

What each ingredient does

Cornstarch
Thickens the cooled liquid into a light, spoonable float.
Egg whites
Whipped into a stiff foam that forms the light topping.
Sugar
Sweetens the syrup and helps the egg whites hold their stiff foam.
Lemons
Add citrus aroma and sharp acidity to the sweet syrup.
Oranges
Provide fresh fruit flavor and juicy body beneath the topping.

The step that matters

Beat the egg whites until stiff. Egg whites need to be whipped until they form firm peaks; under-beaten whites stay runny and will not hold their shape on top of the warm mixture.

Swap the lemon

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

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