What each ingredient does

Loaf sugar
Dissolves to form the syrup and provides the sweetness and body of the candy syrup.
Egg white
Its proteins coagulate when heated, trapping impurities so they rise as scum that can be skimmed off.
Cold water
Dissolves the sugar and forms the liquid base in which the syrup cooks down.

The step that matters

Skimming the scum after each boil. Egg white coagulates and carries impurities to the surface as scum. Removing it fully after each boil keeps the syrup clear, so it must be repeated until no more scum forms.
