Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Sweetens the filling and, when boiled, helps set its firm, smooth texture.
- Cocoa powder
- Provides the chocolate flavour and dark colour of the filling.
- Eggs
- Enrich the filling and help it thicken and hold its body once combined.
- Sweet cream
- Adds fat and moisture, giving the filling a softer, richer mouthfeel.
The step that matters
Boiling to the soft ball stage. Sugar syrup must reach the soft ball stage, where it has enough concentrated sugar to set firm but smooth when cooled. Boiling too little leaves the filling runny, and boiling too long makes it stiff and grainy.
