Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the filling and add richness and structure as they set with heat.
- Flour
- Thickens the chocolate filling so it sets firm enough to slice.
- Sugar
- Sweetens the filling and helps give the meringue its golden browning.
- Baker's chocolate
- Provides the chocolate flavour and body of the filling.
- Sweet milk
- Forms the liquid base that the yolks and flour thicken into custard.
The step that matters
Cook the filling until thick. Egg yolks and flour thicken only when the mixture reaches a simmer-level heat while stirred constantly. Stopping too early leaves a runny filling, and letting it sit too long over heat can scorch or curdle the yolks.
