What each ingredient does

Finely ground coffee
Provides the main coffee flavour that is extracted into the brewed drink.
Egg
Its proteins bind to the coffee grounds and help clarify the liquid as it settles.

The step that matters

Boil for 3 minutes, no longer. Extended boiling over-extracts the grounds and makes the coffee bitter. A short boil, followed by settling, extracts flavour while keeping the brew clear and smooth.
