What each ingredient does

Sponge cake: Provides a light, porous base that soaks up moisture from the cream.
Whipped cream: Adds moisture and richness and fills the space between the cake layers.
Sugar: Sweetens the cream and balances the tartness of the lemon.
Lemon juice: Adds acidity that brightens the richness of the cream.
