What each ingredient does

Coffee
Provides the main flavor and aroma of the drink.
Egg
Helps gather fine grounds so the brewed coffee comes out clearer.
Cream
Adds richness and a smooth, soft texture to the coffee.

The step that matters

Keep the final brew below boiling. After the first boil, the remaining water should only stand without boiling. Continued boiling pulls out more bitter compounds from the grounds and can make the coffee harsh.
