Blueberry and Chocolate Entremet

Blueberry&Chocolate Entremet-9


I have been thinking over and over again about this cake. I’ve been deliberating the different elements, which combined, would create the perfect treat. I made this cake for the birthday of a dear friend. And while I love to bake for special celebrations, I am also quite intimidated.

I usually put a lot of effort in coming up with, what I think, should be the most appropriate treat for the occasion. Then I compose the dessert, and generally, there are quite a lot of elements. Somehow, I always make it very complicated. And after that, I become very unsure. You see, the desserts I come up with, are usually cakes. And you can not try I cake beforehand. Sometimes I reserve a little form each layer and make a few glasses, supposed to resemble the cake, but it’s not the same. I hope that assurance comes with experience, and that I’ll get there some day.

The cake, that I came up with this time, was an Entremet. Because, in my head, when thinking about a special dessert, Entremet wins every time. And so the blueberry and chocolate entremet was born, and even though I would change some thinks when I make it again, I think that the result was quite satisfactory.

This is not an easy dessert to put together. The different elements are easy to execute but are a lot, and definitely time consuming, so I suggest starting a few days in advance if you decide to do this, or any entremet.

I recommend scheduling the processes the following way:

Day 1 – Prepare the sponge, the blueberry puree and the syrup. You need to make the sponge at least one day before soaking it with syrup for best results.

Day 2 – Prepare the chocolate cremeux, the mousse, the crunch ,and the gelee. Layer the elements and freeze overnight.

Day 3 – Prepare the glaze and finish the dessert at least 5 hour before serving. The glaze needs to set and the entremet needs time to thaw.

The biggest effort is during day 2.
