I made a Queen of Sheba cake from Joy of Cooking (basically a chocolate torte with a bit of nuts - I used hazelnuts) for a friend's birthday. I tasted a bit of the cake and find it too sweet, with hardly any nut flavor at all.
How should I ice and decorate the cake to improve the overall flavor? I was thinking whipped cream with toasted hazelnuts and grated chocolate. Would a bittersweet chocolate glaze be better for making the flavor a bit... darker?
