Hot Chocolate Mousse, aka “ChocoBubbles”

Back in 2006 I was partner in an avant-garde dessert bar called “Room 4 Dessert” in New York. It was a molecular think-tank for people with a sweet tooth and while things didn’t always run smoothly it was a very interesting experience for all of us involved. We didn’t have what it took to turn it into a commercial success but for the two years we were open we managed to attract a lot of attention from the medias, and visits from chefs like Thomas Keller, Jean-Georges and Grant Achatz among many others. I wasn’t doing the cooking but one of my favorite dessert from the opening menu was what we called “chocobubbles” and consisted of a warm chocolate “foam” with apricots, cocoa crispies and Pedro Ximenez sherry. It was one of our simplest but most clever menu item.

The hot chocolate mousse could be enjoyed all by itself but feel free to add layers of chocolate chunks, rice crispies or macerated apricots or cherries for texture and surprise. Of course you’ll need a iSi thermo whipper and some N02 chargers. Just pour the hot chocolate in the bottle, charge it with two N02 charger, shake it hard, and keep it warm in a bain-marie if not using right away. This is also a great hot chocolate recipe on its own, if you don’t have an iSi whipper. Enjoy!

  • Hot Chocolate Mousse, “ChocoBubbles”

  • Serves 4
    • For the Hot Chocolate Mousse :

    • For the Hot Chocolate Mousse:

    • Dissolve the cornstarch in the remaining milk and whisk it into the hot chocolate mixture. Cook on low heat, whisking constantly until the chocolate thickens, approximately 5 minutes.
    • Remove from the heat, add the vanilla extract and rum if using, and whisk until smooth.
    • Pour the hot chocolate into a iSi Thermo Whipper, place the top on, and charge with 2 N02 chargers. Shake vigorously.

    Wow, I love how simple this dessert is.  And it sounds like it’d be wonderfully delicious!  Make mine with rum, please.  And layering with the extras?  Great texture and yet more flavor.  I’m going to have to get me one of those iSi Thermo Whippers!  Fun, sophisticated dessert – thanks.

    Wow! You say isi ThermoWhipper, is this a special thing Can you just use a regular cream whipper mine is kaiser not isi? Had an amazing dessert at le farcon in la tania, France recently, a delicious soup of warm chocolate mousse with surprise crunchy pieces hidden inside and a quinnel each of dark and white chocolate.

  • zenchef

    Yes, you can use a regular cream whipper. The thermo is useful to keep the content warm for a longer period of time but if you plan on using it right away the regular version is fine. That dessert sounds good!
