Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Egg white
Helps clarify the brewed coffee, as its proteins trap grounds when heated.
Ground coffee
Provides the main coffee flavor and aroma.
Sugar
Adds sweetness and softens the texture of the frozen drink.

The step that matters

Letting the coffee boil for one minute. Boiling the coffee briefly extracts flavor, but boiling too long makes it bitter. Then the slow simmer on the back of the range keeps it hot while the grounds settle for clearing.
