Chocolate Mousse
This is a study in temperature management. If the chocolate is too hot, the eggs scramble; if too cold, it seizes into lumps before you can finish the fold.
Control your thermal baseline
The chocolate must be warm enough to remain liquid but cool enough to touch comfortably before it meets the yolks. Have everything measured and ready before you start, as the folding phase happens fast.
- large mixing bowl
- heavy-bottomed saucepan
- balloon whisk
- silicone spatula
- bain-marie or double boiler
What goes in.
- 6 ozbittersweet chocolate (60% to 70% cacao), chopped
- 4large eggs, separated
- 2 tbspunsalted butter
- 1 tbspgranulated sugar
- pinchsea salt
Maintaining the Aeration
Use a wide, circular motion with the spatula, cutting down the center and sweeping up the sides. If you use a stirring motion, you will pop the air bubbles you worked to create in the egg whites.
The method.
Melt the chocolate
Place chocolate and butter in a bowl over a pan of barely simmering water. Stir occasionally until smooth, then remove from heat. Let it sit until it reaches room temperature.
Incorporate the yolks
Whisk the egg yolks into the slightly warm, not hot, melted chocolate one at a time. The mixture will thicken and become glossy.
Whip the whites
Beat the egg whites with a pinch of salt until they turn opaque. Add the sugar and continue whipping until soft, pliable peaks form. Do not over-beat to stiff peaks or the whites will be too dry to fold.
Combine
Add one-third of the egg whites to the chocolate mixture. Whisk them in aggressively to lighten the texture. Gently fold the remaining whites in two batches, using a light hand.
Set
Transfer the mixture to serving glasses. Refrigerate for at least 4 hours to let the fats in the chocolate solidify and the structure stabilize.
Other turns to take.
Coffee Infused
Dissolve a teaspoon of high-quality espresso powder into the melting chocolate.
Orange Scented
Add the zest of half an orange to the chocolate base before folding in the egg whites.
When it doesn't go to plan.
Ensure your bowl is completely clean and free of grease before whipping whites, or they will not gain volume.
Do not let any yolk contaminate the whites, as even a trace of fat will prevent them from foaming.
Use a chocolate you would enjoy eating on its own, as its flavor dominates the final dish.
The ones that keep coming up.
Why did my mousse turn out grainy?
The chocolate was likely too hot when you added the eggs or the whites, causing the cocoa butter to seize into small chunks.
Can I use pasteurized eggs?
Yes, they work perfectly fine and provide the same structure as standard eggs.
