This flavour combination is inspired by a dessert called “Goma Street” from Sokyo. It is a unique yet perfect combination of flavours. The black sesame provides a bitterness and comforting nuttiness that pairs so well with the sweetness and creaminess of the caramelized white chocolate mousse. It’s a must try!

Special Tools used for this Recipe

Stand mixer

The stand mixer is a great tool in this recipe to help you do something in parallel (since there’s lots to do!). It is used to whip up the cream for the caramelized white chocolate mousse or to create the meringue in the black sesame dacquoise.

The stand mixer is an investment, but it is used in countless dessert applications such as meringues, cake and cookie batters and choux pastry. We recommend a good quality stand mixer such as this one which will last through years of dessert making.

Hand blender

The hand blender (a.k.a, immersion blender or stick blender) in this recipe, is used to create a perfect emulsion for the dark chocolate cremeux, the black sesame cremeux and the caramelized white chocolate mousse ganache. It is also used to make sure the glazes are completely smooth, emulsified to achieve that perfect mirror shine and so that the colour is evenly incorporated.

The hand blender is one of our most used tools. It is used in so many recipes and techniques and helps you achieve perfect emulsions.
