The recipe,
step by step

1. 1

   Milk Chocolate Brownie

   Combine the butter, sugar and dark brown sugar using a flat beater. Gradually add the eggs. Add and combine the pre-sifted flour, baking powder and coarsely ground fleur de sel. Lastly, add the chocolate covering melted at 45°C and the walnuts. Check that the mixture is properly emulsified but not whipped. Pour the preparation into the buttered oval tart rings (400 g) and smoothen the surface. Fan bake at 160°C for 30 min. 

2. 2

   Banana Compote

   Dice the bananas and mix with the lemon juice. Heat the cream with the nutmeg and vanilla. Allow it to infuse for 15 min. Take a small portion of the sugar and mix it with the pectin NH. Make a dry caramel with the rest of the sugar, then add the butter and warm cream to stop the cooking process. Add the pectin mixed with the sugar, then add the bananas. Cook for a few minutes to slightly stew the bananas. Pour into the square tin, smoothen the surface, let it set in the refrigerator, then cut out 24x5 cm strips. 

3. 3

   Chocolate Mousse

   Mix the gelatin with the water for hydration. Make a custard sauce with the egg yolks, the milk and the Excellence cream (1). Melt the dark chocolate at 45°C, add the melted gelatin mass and the custard sauce once cooked, emulsify. Mix. Heat the egg whites with the glucose, then whip to create the cold meringue. When the chocolate custard mixture reaches 30°C, add the whipped cream (2) and the cold meringue. Pipe 350 g per thermoformed tin, then place the banana insert. Smoothen the surface and let it set in the refrigerator.
