Why it works: Cream and sugar are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cream
- Whipped to stiff peaks, it traps air and gives the mousse its light, airy texture.
- Egg yolks
- They emulsify with the coffee and thicken the mixture, giving it a rich, smooth body.
- Sugar
- It adds sweetness and softens the texture of the chilled mousse.
- Coffee
- It provides the main flavor and the liquid that dissolves the sugar.
The step that matters
Pack in salted ice. Salt lowers the melting point of ice, so the salted ice becomes colder than plain ice. This lets the cream mixture freeze firm over the 3 hours, and the mold must be sealed so brine cannot leak in.
