What each ingredient does

Prunes
Provide the main body, sweetness and fruity flavor of the soufflé.
Eggs
Whites are beaten to create the airy foam that gives the soufflé its lift and structure.
Granulated sugar
Stabilizes the beaten egg whites and adds sweetness to the mixture.

The step that matters

Beating the egg whites until very stiff. Egg whites trap air when whipped to stiff peaks, and that foam provides the lift and light texture of the soufflé. If they are under-beaten, the foam collapses and the soufflé turns dense.
