Plenitude – Salted Caramel Chocolate Mousse Domes

Print Friendly, PDF & Email

I like to try and copycat desserts I tasted in different bakeries and patisseries all over the world. You can find various copycat recipes all over the blog, such as Starbucks copycat blueberry muffins; and – from my top favorite French pastry chef – Pierre’ Herme’s Montebello, which is a strawberry and pistachio entremets.

Trying to copycat a favorite cake or dessert I tasted isn’t always an easy task and requires some experience and patience. These salted caramel chocolate mousse domes are also a Pierre Herme’s copycat from his amazing boutiques. These delicious entremets are made of a crunchy crust topped with salted caramel chocolate mousse, which is glazed with chocolate mirror glaze. The decoration is my favorite part: beautiful dark and white chocolate sheets that are arranged like a Mosaic.

These entremets require mostly following the preparation method, but also quite a lot of patience for the decoration part. It takes time to assemble the chocolate sheets one-by-one, but the result is simply breathtaking. If you like baking challenges – this one’s for you!
