In this petit gâteau we wanted to create 5 different textures in which we could enhance the flavor of the main ingredient: the hazelnut. We combined it with water, instead of dairy, to preserve the hazelnut flavor. The 5 textures of this petit gâteau are: a hazelnut crunchy, a hazelnut mousse, a hazelnut sponge cake, a semi-liquid hazelnut creamy, and a hazelnut coating.
