Why it works: Apple and sugar are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 16,478 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tart apple
- Provides moisture and tart flavour that balances the sugar.
- Sugar
- Adds sweetness and helps give the filling body as it is beaten.
- Egg white
- Whips into foam during beating, giving the filling lightness and structure.
The step that matters
Beating for twenty minutes. Long beating traps air in the egg white and dissolves the sugar, which gives the filling its light, stable texture. Stopping early leaves a dense, runny result.
