Definitely trying the Ginger and Walnut Carrot Cake! Is there anything I could substitute the crystallised ginger with?
Nigella's Ginger And Walnut Carrot Cake (from Nigella's new book AT MY TABLE) has nuggets of chopped crystallised ginger embedded into the cake and sprinkled over the cream cheese frosting. They bring a spicy, zingy element to the cake. Crystallised ginger can be bought in many supermarkets and on-line and is sometimes labelled as candied ginger or glace ginger. If you can buy preserved ginger (which is sold in a jar in syrup) then this could be used as an alternative. Use exactly the same quantities of drained preserved ginger and before using blot each piece of ginger with kitchen paper to remove as much syrup as possible.
If you don't like ginger, or can't find the preserved ginger either, then it is possible to make the cake without the crystallised ginger, though then it becomes a plainer but still delicious Walnut And Carrot Cake. If you can buy candied or crystallised pineapple then we suspect that this would be an interesting alternative, used in the same quantities, to make a tropical version of the cake.
