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

What each ingredient does

Egg yolks
Thicken the sauce as their proteins set when gently heated.
Granulated sugar
Sweetens the sauce and balances the bitterness of the coffee.
Strong brewed coffee
Adds a roasted, bitter flavor that gives the sauce its character.
Whipped cream
Adds fat and air, making the finished sauce light and creamy.

The step that matters

Cooking the coffee and yolk mixture over the double boiler. Egg yolks thicken as their proteins set with gentle heat, but they curdle or scramble if overheated. Constant stirring spreads the heat evenly and keeps the sauce smooth.
