Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Mixed with the grounds, it helps clarify the coffee and keeps the grounds settled.
- Cream
- Adds richness and a smooth, mellow body that softens the coffee's bitterness.
- Egg white
- Beaten and folded into the cream, it adds a light, airy foam on top of the cup.
- Coffee
- Equal parts Mocha and Java provide the main coffee flavor and aroma.
The step that matters
Let the coffee sit hot, but not boiling, for 5 to 10 minutes. Boiling the coffee again after brewing can make it taste harsh and bitter. Holding it just below a boil lets the grounds settle while the flavor stays smooth.
