Making Dark Chocolate Mousse
A proper mousse doesn't require gelatin or stabilizers if your technique is sound. It is a study in texture, transforming heavy cream and eggs into something that holds its own shape while dissolving instantly on the tongue.
Temperature is everything.
Ensure your melted chocolate and egg mixture are at similar, lukewarm temperatures before combining. Working too quickly or with extremes in temperature will break the emulsion.
- Large mixing bowl
- Electric hand mixer
- Rubber spatula
- Small saucepan
- Six ramekins or small glasses
What goes in.
- 8 ozbittersweet chocolate, chopped
- 4large eggs, separated
- 1 cupheavy cream
- 2 tbspgranulated sugar
- pinchfine sea salt
Preserving the Air
Use a wide rubber spatula to cut down through the center and sweep around the bottom of the bowl. Rotating the bowl with your opposite hand as you move, you maintain the volume of the egg whites while distributing them through the heavier base.
The method.
Melt the chocolate
Place the chocolate in a heatproof bowl set over a pan of barely simmering water. Stir until smooth, then remove from heat and let it sit until it feels just warm to the touch.
Prepare the yolks
Whisk the egg yolks into the warm chocolate one by one. The mixture will thicken and become slightly glossy.
Whip the whites
In a clean bowl, beat the egg whites and salt until soft peaks form. Gradually add the sugar and continue beating until stiff, upright peaks hold when you lift the whisk.
Whip the cream
In a separate chilled bowl, whip the heavy cream until it reaches the consistency of soft yogurt; do not over-whip into butter.
Combine
Stir a third of the egg whites into the chocolate to lighten it. Gently fold in the remaining whites, then fold in the whipped cream until no white streaks remain.
Chill
Divide the mixture into ramekins. Refrigerate for at least four hours until fully set.
Other turns to take.
Coffee Infused
Dissolve a teaspoon of instant espresso powder into the melted chocolate for a deeper, bitter profile.
Citrus Zest
Fold in the finely grated zest of one orange during the final step for brightness.
When it doesn't go to plan.
Ensure the bowl used for egg whites is completely free of grease or they will not whip to volume.
If the chocolate base cools too much and becomes too stiff, place the bowl back over warm water for ten seconds.
Avoid using chocolate chips, as they often contain stabilizers that affect the final texture; use a high-quality baking bar.
The ones that keep coming up.
Why does my mousse taste grainy?
This usually happens when the chocolate is either overheated or mixed with the eggs while still too hot, causing the cocoa butter to separate.
Can I make this ahead of time?
Yes, it holds well in the refrigerator for up to 24 hours. Beyond that, the texture begins to lose its initial lightness.
