Instructions
-
Break the dark chocolate into small pieces into the small heatproof bowl. Set the bowl in a larger bowl of hot tap water and let it stand, stirring now and then, until the chocolate is fully melted and smooth. Keep the water out of the chocolate.
~8 min
Gentle indirect heat melts chocolate evenly without scorching, and keeping water out prevents seizing, which turns it into a stiff, grainy mass.
-
Whip 250 ml of the cream with the sugar and vanilla in the large mixing bowl until it holds soft peaks, about 3 minutes. Do not take it past soft peaks or it will turn grainy when folded in.
~3 min
Soft peaks still flow and fold easily; over-whipped cream breaks into butterfat grains and gives a heavy, pasty mousse.
Whisking Whip steadily and watch for soft peaks that droop gently when the whisk lifts. Stop there; over-whipping breaks the cream and turns it grainy.
-
Stir the chestnut puree and the pinch of salt into the melted dark chocolate until evenly combined. The mixture will be thick.
~3 min
Adding salt now lets it dissolve evenly into the warm chocolate, sharpening its flavor before the cold cream dilutes it.
The pinch of salt is not optional seasoning: it sharpens the dark chocolate and keeps the chestnut from tasting flat. Add it to the chocolate before the cream goes in so it dissolves evenly.
-
Loosen the chestnut mixture with the remaining 50 ml cream, stirring until it drops from the spoon. Fold in the whipped cream in three additions with the spatula, cutting down and turning the bowl, just until no streaks of cream remain.
~4 min
Loosening the base to a similar texture and folding gently in batches preserves the air in the whipped cream, keeping the mousse light.
Fold the whipped cream in three additions and stop the moment the last streaks disappear. Overworking deflates the cream and gives a heavy, pasty mousse instead of a dense but tender one.
Folding Cut down through the mixture with the spatula, turn the bowl, and lift. Fold in three additions and stop as soon as the last streaks vanish to keep the air in.
-
Spoon the mousse into the serving glasses, tapping each one on the counter to settle it. Cover and chill until firm enough to hold a spoon upright, at least 4 hours.
~240 min
Chilling lets the melted chocolate re-solidify and the mousse set firm; tapping releases trapped air pockets for a smooth texture.
-
Serve the mousse straight from the fridge, with a small extra pinch of salt over the top if you like.
