Y'know, I never think to look on Wikipedia. Thanks Andy. This one has candied orange peel and dried currants. Interesting. The note on this recipe is that the almond paste sinks to the bottom and gives a sticky top when the cake is turned out. So, no layer in the middle but rather on the top of almond paste.
