This cake was created by Shanna Masters, served at a dinner honoring some of San Francisco's top chefs. It is best when allowed to "mellow" for a day. I serve it sliced, with a light spreading of Lemon Curd, topped with heavy whipped cream (preferably not from a can) and fresh blueberries or raspberries. Be careful not to over-bake this cake, or it will be dry. Bottled lemon juice may be used in place of fresh lemon juice.
