Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mocha coffee and java coffee
- Provide the main coffee flavor and aroma of the drink.
- Egg
- Mixed into the grounds to help them settle, leaving a clearer brew.
- Cream
- Adds richness and body, softening the bitterness of the coffee.
- Egg white
- Beaten into the cream mixture to add a light, airy foam.
- Sugar
- Adds sweetness to balance the coffee.
The step that matters
Let it froth, then stir down the grounds and boil for 5 minutes.. Stirring the grounds down after frothing, then boiling, helps them sink with the egg so the coffee stays clear. Skipping the stir leaves grounds suspended in the cup.
