What each ingredient does

Barberries
Provide the tart fruit flavour and the jam base that the biscuits are built from.
Powdered sugar
Sweetens the barberry mixture and adds bulk to the jam so it can be shaped.
Eggs
Egg whites whipped to stiff peaks add foam and lightness to the mixture.

The step that matters

Whisking the egg whites to stiff peaks. Egg whites must be whipped until they hold stiff peaks, because their foam traps air and gives the mixture its light structure. Under-whipped whites will not hold the shape, and over-whipped whites turn grainy and collapse when folded in.
