This recipe of a traditional
French cake comes straight from a great, beautiful book on chocolate techniques
and recipes. I made just a couple of minor changes and the result was delicious. The book is Cooking with Chocolate – Essential Recipes and Techniques, edited by Frederic Bau.
INGREDIENTS FOR 10-12 PEOPLE:
ALMOND DACQUOISE
1/3 cup (1 ¼ oz / 35gr)
all-purpose unbleached flour
1 cup plus 3 tablespoons (3 ½
/ 100gr) ground almonds
1 cup (4 ¼ oz / 120gr)
confectioners’ sugar
6 (6 oz / 170gr) egg whites
1/3 cup (2 oz / 60gr) sugar
CRISP PRALINE
3.5 oz (100gr) milk chocolate, 40% cocoa1 ½ oz (80gr) crushed crepes dentelles
(wafer-like biscuits also sold on Amazon.com)
7oz (200gr) homemade praline
(a paste of nuts and sugar – see below for recipe)
7 ½ oz (220gr) dark
chocolate, 70% cocoa
2 egg yolks
5 teaspoons (2/3 oz / 20gr)
sugar½ cup (100ml) whole milk
Heavy cream, divided as follows:
1 ¼ cup (300ml) and
1 ½ cup (400ml)
Prepare your homemade
praline. Preheat the oven to 300 ºF (150ºC). Roast 5 oz (140gr) of hazelnuts or
blanched almonds for about 10 minutes. Leave them to cool for a few minutes and
peel the hazelnuts (for this recipe I used only hazelnuts). Keep in a warm place.
Prepare a caramel with 3 ½ oz (100gr) of sugar, preheating a saucepan and pouring in one third of the sugar. Stir constantly until it reaches a uniform caramel color. Add the next third of the sugar, stirring constantly. Then pour in the remaining third, still stirring constantly, until the sugar caramelizes completely.
Incorporate the roasted nuts, stirring quickly until thoroughly combined, and immediately smooth out over a silicone sheet or sheet of parchment paper. Leave to cool at room temperature. Then break up the praline into medium chunks and place them into the bowl of a food processor and process until you have a smooth paste.

Prepare the almond dacquoise, which is a light soft meringue that has nuts folded into it and is baked in a thin layer. Preheat the oven to 350ºF – 375ºF (180ºC - 190ºC). Sift the flour with the ground almonds and the confectioners’ sugar into a mixing bowl.
Whisk the egg whites with the sugar, until soft peaks are formed. When whisking the whites, make sure that the bowl is perfectly clean and dry and that the whites are at room temperature. Always add a pinch of salt, use medium speed and stop when you obtain soft peaks (like shaving foam or styling mousse), not stiff peaks.
Carefully fold in the sifted
dry ingredients with a flexible spatula. Spread it out evenly over the silicone
mat or a parchment paper sheet. Bake for about 15 minutes, until a nice golden
color.
Now it’s time to prepare the
crisp praline. Chop the milk chocolate and melt it slowly in a bain-marie.
Crush the wafer biscuits. Incorporate the praline into the melted chocolate,
and then carefully stir in the crushed crepes dentelles.
Prepare a 9.5-10 in.
(24-26cm) springform pan (a hinged pan) putting a parchment paper sheet at the
bottom. Cut the dacquoise base out into a circle slightly smaller than the pan,
put it at the bottom of the pan and cover it with the crisp praline. Place in
the refrigerator.
The last step of this
preparation is the bittersweet chocolate mousse. Chop the chocolate and melt it
slowly in a bain-marie. In a mixing bowl, beat the egg yolks with the sugar
until thick and pale. Add the milk and 1 ¼ cup (300ml) of heavy cream, pour the
mixture into a saucepan and simmer over low heat. The temperature should not
rise over 183ºF (84ºC). The only purpose of this step is to melt the sugar and
smooth the mixture. Overheating it can cook the eggs and ruin the cream. Remove
from the heat and pour the custard through a mesh strainer into a mixing bowl.
Process for a few seconds with an immersion blender for a smooth, creamy
texture. Gradually and very slowly pour the custard over the melted chocolate,
mixing energetically. Process with an immersion blender for a perfect texture.
Whip the remaining heavy cream with an electric blender until it is lightly whipped. Both the bowl and the heavy cream have to be well-chilled. When the chocolate mixture reaches a temperature of 113ºF – 122ºF (45ºC – 50ºC), fold in the whipped cream, carefully and softly, with a flexible spatula.

Pour this chocolate mousse into the pan and place in the freezer immediately and freeze for at least 12 hours. A few hours before serving remove the cake from the pan and put in the refrigerator for at least 6 hours. Serve it only when it is completely defrosted. Decorate with praline, cocoa powder and whipped cream.
