What each ingredient does

Egg whites
Beaten into a stiff froth, they trap air and give the sauce its light, airy foam.
Sugar
Dissolves into the boiled syrup, adding sweetness and helping the foam hold its shape.
Fruit juice
Adds flavour and acidity to the sauce.

The step that matters

Folding in the beaten egg whites. Stirring rather than folding deflates the stiff foam, so the sauce loses its lightness. Fold gently and quickly, then serve straight away before the foam collapses.
