Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Egg whites
Beaten into a foam that traps air, giving the souffle its light, airy structure.
Gelatine
Sets the mixture as it cools, so it holds its molded shape.
Sugar
Adds sweetness and helps stabilise the foam when beaten into it.
Lemon juice
Adds acidity that brightens the flavour and balances the sweetness.

The step that matters

Gently fold the beaten egg whites into the gelatine mixture. The air bubbles in the beaten whites give the souffle its lightness. Stirring vigorously pops those bubbles and deflates the mixture, so fold slowly with a spatula until just combined.
