Why it works: Gelatin and cream match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 1,628 recipes. Both carry acetic acid, which smells sour, vinegar. The science ↓
Coffee Mousse
Ingredients
Directions
Prepare the coffee
Dissolve gelatin in cold water and set aside.
Prepare black coffee using 2 tablespoons coffee and 2 cups water, filtering twice.
Combine coffee, sugar, and hot water. Stir until sugar dissolves.
Add the dissolved gelatin to the coffee mixture.
Set and mold
Strain the mixture to cool, stirring occasionally.
Once partially set, beat the mixture until foamy.
Fold in the whipped cream gently.
Pour into a mold. Cover.
Pack in ice and salt.
Let stand for 4 to 6 hours before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatin
- Sets the liquid into a light, firm structure as it cools.
- Whipped cream
- Adds air and fat, giving the mousse a light, creamy texture.
- Sugar
- Sweetens the coffee and balances its bitterness.
- Black coffee
- Provides the main flavor and aroma of the mousse.
The step that matters
Fold in the whipped cream gently. Heavy stirring deflates the air bubbles in the whipped cream and the partly set mixture, leaving a dense rather than light mousse.
