    Whisk eggwhites in an electric mixer until firm peaks form (2-3 minutes), gradually add sugar, whisking until thick and glossy. Fold into chocolate mixture, then fold in hazelnut mixture. Spoon into a 22cm-diameter buttered and base-lined springform cake tin and bake until a skewer withdraws clean (30-35 minutes). Cool completely in tin, remove, dust with extra cocoa and serve with crème fraîche and roast rhubarb. Store at room temperature. Best eaten on day of making.
