I found this recipe on the net and whilst I usually prefer easy recipes, sometimes I feel like putting in extra effort. This is one of those recipes and the final results are well worth it.
1. Pre-heat the oven to 180°C.
2. Place the egg whites in a bowl with the lemon juice and vanilla sugar. Whisk into stiff peaks.
3. Fold in the icing sugar and ground almonds.
4. Tip onto a baking tray covered with baking paper, spread to an equal 2 cm thickness.
5. Bake for 30 minutes in the oven, so that it is still soft. Leaving the oven door slightly open whilst baking.
1. Blend the chestnut puree with the rum.
2. In another bowl, beat the butter until soft, then add the chestnut puree and mix well.
3. Whip the cream into stiff peaks and fold into the chestnut mixture.
4. Finally add the chopped chestnuts (if using).
Assembling the dessert
1. Take a saddle tin and carefully lift the dacquoise into it.
2. Spoon the mousse inside and smooth flat.
3. Now make sure you have enough dacquoise exposed to fold over the mixture, sealing it like a parcel.
4. Place in the freezer for 2-3 hours, then remove it from the mould.
5. Sprinkle with cocoa powder before serving.
