Hazelnut mystery log

Hazelnut Mystery Yule Log

Here is a new log idea for your Christmas meal. You will enjoy!
As I was completely under the spell of this very pink mystery log with raspberries and ruby ​​chocolate, I kept the same presentation, only changing the flavors. When the log is cut, we discover a rolled biscuit. I find it so beautiful and appetizing.


This yule log consists of a whipped hazelnut ganache, made according to Cédric Grolet’s recipe. She is perfect ! I had already tested and appreciated it in a peanut version, in this kakahuète cake.

You will need hazelnut praline. The recipe is here.
For the biscuit, this time I chose to stick with Christophe Felder’s proposal. This is a fluffy sponge cake. It is a little more difficult to work than the choux pastry biscuit, but with a little precaution, it rolls up without much difficulty. This roll is filled with a gianduja ganache. A few slivers of hazelnuts add crispness to the whole.


This log is very accessible in its realization. There are no complicated steps, and if you follow the recipe carefully, it should be easy to do.



It will be a hit with your guests.

We loved it. The ganache is extremely light, delicately scented. It’s a real pleasure with every bite.

Add them in several times to the dough, using a spatula.


Spread this dough on a baking mat (Flexipat 25X35).

Coarsely chop the hazelnuts and spread them over a piece of the dough, the size of the log mould. This will be the piece to put at the bottom of the log.

Assembly:



Cut the biscuit so as to have the base of the log covered with hazelnuts and the biscuit to be rolled.



Spread the cooled ganache over it.

Roll gently, tightly.
Stop when the size feels right for you. (Eat the rest while drinking a little coffee.)
Book cool.


Whip the ganache into whipped cream.



Half line a log mold covered with a mat or a sheet of rhodoïd.

Cut the edges of the roll and put it in the center of the log.
Cover with remaining mousse. Smooth.
Arrange the biscuit, hazelnuts against the mousse.


Freeze.



Take the log out a few hours before tasting to give it time to thaw.

Decorate as you wish. I used a brown velvet spray on the frozen log, then layered praline leaves and edible gold leaf.

To finish: for the log mold I used the same Silikomart mold as here or there with this time the smooth mat.


For velvet spray, preferably choose a good brand. That one is the best I’ve used so far.

I love using chocolates from chocolatiers for my yule log decorations. The praline leaves had been sent to me by Fabrice Gillote. A delight!


The presentation remains a suggestion. It’s up to you to let your creativity speak.



I accompanied this log with a cider. I tell you more about instagram
