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

What each ingredient does

Coffee
Provides the main coffee flavor and aroma in the brewed drink.
Ground chicory
Adds a roasted, slightly bitter flavor and body to the coffee.
Egg (with shell)
Its shell and white bind fine grounds so they settle, clearing the liquid.

The step that matters

Stir until scalding hot, without boiling. Boiling can over-extract bitterness and keep grounds suspended, so the coffee is held just below the boil while it steeps.
