This, an adaption of Claudia Roden's magnificent orange and almond cake, is a wonderfully damp, dense and aromatic flourless cake: it tastes like one of those sponges you drench, while cooling, with syrup, only you don't have to. And it's such an accommodating kind of cake, too: it keeps well, indeed it gets better after a few days; and it is perfect either as a pudding with creme fraiche, or as a sustaining slice with a mug of tea at any time of the day. And please read the Additional Information section at the end of the recipe before proceeding. For US cup measures, use the toggle at the top of the ingredients list.
