  4. Dissolve the gelatine in water and add it to the mixture.

Make and set the souffle

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

What each ingredient does

Eggs
Yolks enrich and thicken the base, while whites whisked to stiffness give the souffle its airy lift.
Gelatine
Sets the mixture so the light souffle holds its shape when chilled.
Castor sugar
Sweetens the base and helps the yolks whisk to a thick, stable cream.
Lemon
Provides the main flavour through juice and zest, adding acidity and aroma.

The step that matters

Folding in the egg whites. Whites hold air only when whisked stiff, and overmixing or deflating them while folding loses that lift, leaving a dense souffle. Fold gently and quickly to keep the foam intact.

Swap the lemon
