Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cornstarch
- Swells with heat and thickens the milk into a smooth, sliceable cream.
- Egg
- Adds richness and helps set the cream as its proteins thicken with gentle heat.
- Milk
- Forms the liquid base that the starch and egg thicken into a creamy texture.
- Sugar
- Adds sweetness and slightly raises the temperature at which the custard thickens.
- Vanilla
- Adds aroma and a rounded flavor to the cream.
The step that matters
Stir constantly while cooking. Constant stirring spreads heat evenly so the starch thickens smoothly and the egg does not overheat and scramble into lumps.
