Dark Chocolate Mousse
This mousse relies entirely on the suspension of air within chocolate and fat. You melt high-quality chocolate, fold in whipped cream, and allow the temperature to bring the structure together. It is an exercise in temperature control and patience, requiring nothing more than a whisk and a bowl.
Temperature is your primary ingredient
If your chocolate is too hot, it deflates the cream; too cold, and it seizes into grainy lumps. Aim for the temperature of a warm bath.
- Large mixing bowl
- Balloon whisk
- Rubber spatula
- Double boiler or heatproof bowl over a saucepan
What goes in.
- 6 ozbittersweet chocolate (60-70% cocoa), chopped
- 1.5 cupsheavy cream, cold
- 2 tbspgranulated sugar
- 1 tspvanilla extract
Maintaining Aeration
Use a wide rubber spatula to cut down the center of the bowl and scrape along the bottom. Rotate the bowl as you lift the mixture over itself to trap air without popping the bubbles.
The method.
Melt the chocolate
Place the chocolate in a heatproof bowl over simmering water. Stir until just melted, then remove from heat. Let it sit until it feels neutral to the touch.
Whip the cream
Whisk the cream, sugar, and vanilla in a chilled bowl. Stop when the cream forms soft, drooping peaks that just hold their shape.
Temper the mixture
Stir one-third of the whipped cream into the melted chocolate to loosen the texture. This prevents the chocolate from stiffening when the rest is added.
Fold and combine
Gently fold the remaining cream into the chocolate base. Work quickly but softly until the color is uniform and no white streaks remain.
Set
Divide into glass ramekins and refrigerate for at least 3 hours. The mousse is set when the surface is firm to the touch.
Other turns to take.
Espresso infusion
Dissolve one teaspoon of instant espresso powder into the chocolate while melting.
Citrus zest
Fold in the fine zest of one orange at the final step to brighten the finish.
When it doesn't go to plan.
Use a glass or metal bowl for whipping cream; plastic can retain oily residues that prevent aeration.
If your chocolate seizes or turns grainy, add a teaspoon of warm water and whisk vigorously to bring it back to a smooth emulsion.
Ensure the chocolate is at room temperature before introducing the whipped cream.

Can I use milk chocolate instead?
Milk chocolate contains more sugar and milk solids, which will make the final result much softer and harder to set; bittersweet is recommended for stability.
Why did my mousse separate?
Usually, the chocolate was too hot when folded into the cream, which melted the fat bubbles. Ensure the chocolate is barely warm.
