What each ingredient does

Egg white
Whipped into foam, it gives the icing its light, airy body.
White sugar
Dissolved in water and boiled into syrup, it sets the icing's sweetness and firm structure.

The step that matters

Pouring the syrup over the egg white. The syrup must be cooled slightly first. If it is too hot it can cook the egg white unevenly, and if it is too cool it will not blend smoothly into the foam.
