Ginger and walnut carrot cake: This is very different from the richly sweet, loftily layered and aerated American original. While it is in some senses far more reminiscent of an old-fashioned, slightly rustic English teatime treat, it is, with its ginger-spiked cream cheese icing – only on top, not running through the middle as well – just right to bring to the table, in pudding guise, at the end of dinner, too. #AtMyTable #nigella
