So much in cooking, as in the rest of life I suppose, is about contrast, about balance. Here the acerbic fragrance of the passionfruit undercuts the otherwise over-egged richness of the white chocolate: this gives you flavour, intensity, sweetness and light.

On standing, the clear, sour-sweet juices of the fruit collect under the mousse: place raspberries in the glass first (again contrast, this time of colour, too) and let them become plumply infused and almost headily soused beneath.
