Poussière d’étoile: Chocolate and coffee tart with stardust!

I just got new books last month, large box from Amazon France ^^. I'm so afraid that I won't be able to get it because of the flood. One of the books that I looked foreword to read it is .............. a new book from .................... 

Poussière d’étoile

I love his creativity and his books, you might come across his creative desserts in the Japanese magazine "café-sweets (カフェ-スイーツ)" too. He writes many books on Pastry art. And if you ever read his biography, he started his apprenticeship in his teenage at the Litzler-Vogel in Strasbourg and after that working at Fauchon and Guy Savoy, he became a head pastry chef at the Hotel de Crillon, when he just 23 years old. He had been voted Best Pastry Chef in 1995 and in 2004 he received the honorary title of Chevalier des Arts et des Lettres by the Ministry of Culture. But you don't have to be afraid of his book, because most of them are made for home baker like us ^^.  And  if you can read French I suggest you should buy one of his baking bible :.....................too. It's a big book that will give you many things that you need in baking world. 
For this book, it contains a lot of stunning desserts that's not hard to make. They come with beautiful decorating idea that turn simple dessert into something special.
This recipe that I try is only a simple chocolate and coffee tart, but with the idea of using the semi sphere shape instead of traditional tart pan or ring, makes this tart looks so gooooood! But we can't pay attention only on the look, the taste of this dessert is remarkable too. The rich chocolate cream with a hint of coffee, with Chantilly au café and most of all the caramelized hazelnuts that work as a decoration and taste booster, a lot of it and you will fall in love with this desserts. Poussière d’étoile means stardust, and I think that he name it after the look of the  Chantilly au café that covered with caramelized hazelnuts. So if you want your dessert to be called stardust, don't skip it, it's not hard to make anyway, hehe.
