What each ingredient does

Egg
Clarifies the coffee as it cooks, so the grounds settle and the drink looks clear.
Pure mocha coffee
Provides the main coffee flavour and aroma of the drink.

The step that matters

Boil the mixture until it is perfectly clear. The egg proteins must set around the coffee grounds as the mixture heats, trapping them so the liquid turns clear. Boiling too briefly leaves the drink cloudy and gritty, while boiling too hard can make it bitter and muddy.
