Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the custard as they set when gently heated, giving it body.
- Grated chocolate
- Provides the chocolate flavor and color of the custard.
- Milk
- Forms the liquid base of the custard and carries the chocolate and sugar.
- Sugar
- Adds sweetness and balances the bitterness of the chocolate.
The step that matters
Add the eggs to the hot mixture gently. Eggs set into a smooth custard only when heated slowly. Adding beaten eggs to a mixture that is too hot or boiling can curdle them, so keep the heat low while stirring in the eggs and cooking until thick.
