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

What each ingredient does

Egg
Sets with heat to thicken the custard and gives it structure.
Cornstarch
Thickens the coffee mixture as it heats and holds the custard together.
Whipped cream
Adds airiness and a light, creamy texture to the cooled custard.
Sugar
Sweetens the custard and balances the bitterness of the coffee.

The step that matters

Stir the egg mixture into the hot coffee and let it boil until thickened. Egg proteins set as they heat, but if the mixture gets too hot or is not stirred, the eggs can scramble and turn lumpy. Stirring keeps the heat even while the cornstarch thickens the custard.
