What each ingredient does

Ground coffee
Supplies the flavor that is extracted into the hot water.
Egg white
Coagulates as it heats and traps fine grounds, clarifying the coffee.

The step that matters

Let it settle for ten minutes. The egg white and fine grounds coagulate and sink slowly. Pouring before they have settled can carry sediment into the cup and leave the coffee cloudy.
