What each ingredient does

Eggs
Beaten eggs thicken as they cook, giving the mixture its structure and body.
Water
Boiling water heats the eggs quickly and provides the moisture that makes up the cake.

The step that matters

Adding the beaten eggs to the boiling water. Pouring the eggs in slowly while stirring constantly keeps them from clumping or scrambling. Continuous stirring spreads the heat evenly so the egg proteins set into a smooth, thickened mixture.
