Cake for Alayne

"...And best of all, Lord Nestor’s cooks prepared a splendid subtlety, a lemon cake in the shape of the Giant’s Lance, twelve feet tall and adorned with an Eyrie made of sugar.
For me, Alayne thought, as they wheeled it out. Sweetrobin loved lemon cakes too, but only after she told him that they were her favorites. The cake had required every lemon in the Vale, but Petyr had promised that he would send to Dorne for more."
