Helen Goh's desert island cake.William MeppemIt seems to amuse people that this simple bake is the one I would take to my desert island. It has a very pleasant texture,sort of a cross between a layer cake and a Genoise sponge. Without the acidity and sweet syrup of a lemon drizzle cake,it's an altogether gentler offering,with the fragrance of lemons coming mostly from the zest. You could add a tablespoon or two of poppyseeds for a pop of texture,but raspberries work beautifully for this summer variation.
