Mandarin Torte is one of the many cakes in Germany sold in most bakeshops all over the country. I am not baking and can not always inquire from the sellers what these cakes are made of, but I think it is made with Schmand (sour cream) and topped with pieces/sections  of fresh Mandarin orange. 

Mandarin Torte became one of my favorite cakes while living in the city of Bremen because of the mixture of sweet and sour taste coming from the sour cream and sweet fresh Mandarin. The Mandarin Torte of one of my favorite bakeshops in Bremen , Garde became a favorite and never fails to buy even a piece when i see them on cake display cabinet

Below is a picture of Mandarin Torte which became a part of many wonderful memories I had in Bremen.
