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, syrupy body as it heats.
Egg whites
Add foam and body, and their proteins help the mixture set lightly as it cools.
Sugar
Provides sweetness and body to the syrup.
Citric acid
Adds tartness that balances the sweetness.

The step that matters

Stirring in the beaten egg whites off the heat. Egg whites cook and clump when they meet very hot liquid, so they are added quickly after removing the pot from heat and stirred in to disperse them evenly.
