As a seasoned pastry chef with years of experience crafting elegant desserts, I've perfected this stunning almond Bavarian cake. Preheat the oven to 180°C (thermostat 6).
For the Bavarian cream, prepare a caramel by heating 250 g sugar with 10 cl water until blond. Add 6 cl water and the boiling milk, stirring continuously.
Soften the gelatin sheets in cold water. Whisk the egg yolks with the remaining sugar, then incorporate into the caramel. Cook gently until the mixture coats the spoon. Drain and add the gelatin off the heat, stirring well. Cool completely.
For the biscuit, butter a springform pan. Separate the eggs. Beat the 2 yolks and 2 whites with icing sugar until pale and creamy. Whip the 3 additional egg whites to stiff peaks and fold in gently, along with powdered almonds, melted butter, and flour. Pour into the pan and bake for 40 minutes.
Cool the biscuit, unmold onto a rack, trim the crust, and place in a removable-edge mold. Whip the cream and fold into the cooled Bavarian mixture. Pour over the biscuit and refrigerate for at least 12 hours.
For the sauce, melt the chocolate with 10 cl cream in a saucepan.
Unmold the cake, sprinkle with praline, garnish with cape gooseberries, and serve with warm chocolate sauce for an unforgettable dessert.
