Hello All, Recently I traveled to Japan and decided to stop at Starbucks and see what they sell over there that you might not find in america, one cake caught my eye and I decided to try it. Is the Orange Valencia cake. It is a orange cake with sour cream top and a refreshing jelly. I can not seem to find anywhere a good recipe of how to make it, I have tried different recipes at home and none of them taste the same, I need help I don't know anymore what kind of cake it is exactly and how to make it. I know how it tastes but since I am really new to the dessert making I am lost. Please help.
