Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cream
- Forms a rich, smooth topping that floats on the hot coffee.
- Egg white
- Whipped to stiffness, it lightens the cream and gives the topping a airy texture.
- Sugar
- Sweetens the coffee at the base of each cup.
- Hot strong coffee
- Forms the warm, bold base that the cream sits on.
The step that matters
Beat the egg white until stiff. Egg white must be whipped until stiff peaks form, because the air trapped in its protein network gives the topping lightness. Under-beaten white will not hold its volume when folded into the cream.
