What each ingredient does

Egg white
Binds the coffee grounds and helps clarify the liquid as it cooks.
Ground coffee
Provides the coffee flavor and aroma that the water extracts.
Boiling water
Extracts flavor from the coffee grounds during brewing.

The step that matters

Add 2 tablespoons of cold water. Adding cold water after boiling drops the temperature and helps the grounds sink, so the coffee clears instead of staying cloudy.
