Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Heavy cream
- Whipped into air bubbles that give the mousse its light, airy structure.
- Sugar
- Sweetens the mousse and thickens the coffee into a syrup as it cooks.
- Black coffee
- Provides the main coffee flavor once reduced into a syrup.
- Chocolate
- Adds rich flavor and fat, giving the chocolate mousse body and depth.
- Curacao or noyon
- Adds citrus-orange aroma and flavor to the liqueur mousse.
The step that matters
Whip the heavy cream until stiff.. Whipped cream holds air in a network of fat and protein. Under-whipped cream leaves the mousse runny and flat, while over-whipped cream turns grainy and can separate when folded in.
