I have not yet made this, but I am posting a link anyway just because it just sounds so good and so different, and it is not tagged as a Passover dessert.
Karen, of Citrus and Candy, has a few flourless cakes. There is the requisite chocolate cake (this one with hazelnuts). And there is a recipe for the classic orange cake. But, what really intrigues me is the Flourless Apple and Almond Tea Cake from The Cook’s Larder in Sydney, Australia. Okay, it is a little late in the season for apple cake, but this cake has maple syrup (or honey) and ginger and apples and almonds! I think this is one of the most popular cakes at The Cook’s Larder.
