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

What each ingredient does

Milk
Forms the liquid base that thickens into the cream.
Corn starch
Thickens the milk into a smooth, spoonable cream as it cooks.
Egg yolks
Add richness and help set the cream as they cook.
Sugar
Sweetens the cream and adds body to its texture.

The step that matters

Return the mixture to the saucepan and cook until thickened. Corn starch granules swell and thicken the liquid only when heated to a boil, and egg yolks can curdle if overheated. Stirring constantly and cooking just until thick keeps the cream smooth.
