To change from Yule logs to a rolled cake, I propose a decadent three chocolate log. This recipe has been on the site for over 10 years and is a real success. It is easy to make, it just requires a little time! I used a log mold (a gutter) measuring 30x8 cm. You will notice that there is no gelatin in this recipe, it is normal and the log holds up well. If you prefer to use gelatin, you will need to take 50 g of cream for each mousse and melt 1 sheet of gelatin in it, then add it to the melted chocolate. But it is not necessary! I am just giving you the information because I get a lot of questions about it.
