Why it works: Raspberry and chocolate work together. They rank in the top 12% of all ingredient pairs, and cooks put them together in 457 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg white
- Whipped to stiff foam, it gives the filling a light, airy, creamy texture.
- Raspberry jam
- Adds sweetness, fruity acidity and moisture, loosening the whipped egg white into a spreadable filling.
- Sweet chocolate
- Adds rich flavour and body, firming the filling as it is stirred in.
The step that matters
Gradually add the raspberry jam while beating constantly. Adding the jam slowly while beating keeps the egg white foam from collapsing. Dumping it in at once deflates the stiff foam and leaves the filling dense and watery.
