There's only one Nigella Lawson, and this delicious, fragrant and beguiling cake is one of my all time favourites of her many cakes. With the apricots shining like jewels on the surface along with the chopped Pistachios, and the beautiful flavours of Rosewater and Cardamon within, this cake could proudly be served as the finishing touch to a Middle Eastern Banquet, or as an afternoon tea treat.
