Blueberry Cream Cheese on Lemon Cake. The blueberry puree made the frosting too soupy to pipe 1M roses around the cake, so I had to compromise. Also it is way too hot in the house (no AC in Germany)! I loved the color of the icing, just wish it would have thickened up without adding boxes and boxes of powder sugar and losing the flavor of the blueberry. I think next time I will go with blueberry cake and lemon frosting :)
