Created by Francesco Genovese, Head Pastry Chef at Harrods, the hazelnut and raspberry éclair is a modern dessert that brings together intensity, freshness, and balance. The roundness of hazelnut meets the acidity of raspberry in an elegant and contemporary composition, designed to highlight different textures: soft biscuit, velvety mousse, and a fruity insert.

Its versatility makes it ideal for modern showcase creations, facilitating the pastry chef’s work at every stage of production.
