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.
