Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Double cream
- Whipped into stiff peaks, it gives the filling its light, rich body.
- Egg white
- Whipped with sugar, it traps air that gives the filling lift and a airy texture.
- Sugar
- Stabilises the whipped egg white and adds sweetness to the filling.
The step that matters
Whipping the egg white. Egg white must be beaten to stiff peaks before the sugar is added gradually, so it holds air. Under-whipped whites deflate when folded, and over-whipped whites turn grainy and lose their smoothness.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
