Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Adds sweetness and, as it dissolves and thickens with the milk, helps give the filling body.
- Sweet chocolate
- Provides the main flavour and, as it melts into the milk, thickens the filling.
- Sweet milk
- Forms the liquid base that the sugar and chocolate dissolve into and thicken.
The step that matters
Boiling until thick. The filling thickens as the milk, sugar and chocolate cook down and cool. Stop too early and it stays runny; cook too long and it can scorch on the bottom of the pan or set too firm to spread.
