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

What each ingredient does

Egg yolks
Emulsify the cream and add richness and body to the drink.
Cream
Adds fat for a rich, smooth texture and mellows the coffee's bitterness.
Clear coffee
Provides the main coffee flavour and aroma.
Sugar
Adds sweetness, balancing the bitterness of the coffee.

The step that matters

Let the mixture cool before chilling. Putting hot liquid straight onto ice melts it too fast and dilutes the drink. Cooling first keeps the coffee strong and the texture smooth.
