Step 27:
For the Assembly:
Get your silicone mould ready. I used a 39.6 x 19.3 x 5.1 cm mould. Don’t worry if you do not have this. Use any mould you have readily available and follow the same process. Also remember, we are assembling upside down.Step 28:
Firstly, fill the mould halfway with the mousse. Neatly place the frozen praline paste in the centre and press lightly.
Step 29:
Cover with some more mousse and then a layer of cake on top neatly. Press down to make sure the mousse fills the mould. Freeze for 4-6hours. Preferably overnight.
Step 30:
When ready, make the glaze. Pour the glaze over the cake.
Step 31:
Decorate with Chantilly, nugget and toasted hazelnuts. Serve with a nice cup of coffee.
