Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chocolate cake
- Adds chocolate flavor and body to the milk base.
- Milk
- Forms the liquid base that the custard sets in.
- Egg yolks
- Proteins set with gentle heat to thicken and enrich the custard.
- Sugar
- Adds sweetness and balances the chocolate flavor.
- Corn-starch
- Thickens the custard as it heats and swells in the liquid.
The step that matters
Heating the custard on the stove while stirring constantly. Egg yolks can curdle or scramble if they overheat or heat unevenly. Constant stirring spreads the heat, letting the starch and egg proteins thicken the custard smoothly before it cooks too far.
