Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set and thicken the custard as they cook, giving it body and structure.
- Corn starch
- Thickens the liquid when heated, giving the custard a smooth, firm texture.
- Chocolate
- Provides the main flavor and deep color of the custard.
- Milk (in the method)
- Forms the liquid base that the eggs and starch thicken into a custard.
- Sugar
- Sweetens the custard and balances the bitterness of the chocolate.
The step that matters
Cook the mixture in a double boiler until it thickens. Gentle, indirect heat lets the starch and egg proteins thicken the custard smoothly. Too much heat can scramble the eggs into lumps or scorch the chocolate, so the custard should be stirred and watched closely.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
