What each ingredient does

Egg white
Its proteins trap impurities in the syrup and rise as scum that can be skimmed away.
Maple syrup
Forms the base liquid that is clarified and becomes the finished product.

The step that matters

Boil without stirring. Stirring during boiling breaks up the egg white scum so impurities stay suspended and cloud the syrup. Letting it boil undisturbed lets the coagulated particles rise to the top where they can be skimmed off.
