What each ingredient does

Coffee
Provides the main flavor and aroma of the drink.
Egg
Its proteins set during heating and gather the coffee grounds so they settle out of the liquid.

The step that matters

Remove from heat and add a small amount of cold water. Once the egg proteins have set around the grounds, the cold water helps the grounds settle to the bottom. Skipping this or leaving the pot on the heat can leave the coffee cloudy and gritty.
