Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Baker's chocolate
- Provides the main chocolate flavour and body to the filling.
- Sugar
- Adds sweetness and dissolves into the mixture to help it set firmer.
- Butter
- Adds fat for a smooth, rich texture in the filling.
- Sweet milk
- Forms the liquid base that melts the chocolate and carries the other ingredients.
The step that matters
Boil while stirring continuously. Boiling thickens the mixture as it cooks down, and constant stirring keeps the chocolate and milk from scorching on the bottom of the pan. Scorched chocolate tastes bitter and burnt.
