What each ingredient does

Barberries
Provide the tart fruit flavour and the jam-like body of the filling.
Powdered sugar
Sweetens the filling and helps it set firm as it dries.
Egg whites
Whipped to stiff foam, they give the filling its light, airy structure.

The step that matters

Whisking the egg whites until stiff. Egg whites hold air only when whisked to stiff peaks. Under-whisked whites deflate when folded into the barberry mixture, leaving a dense, weepy filling that will not dry properly.
