Sometimes I want traditional icing, sometimes I want buttercream and sometimes I want cream cheese or sour cream icing, and who knows what I will want tomorrow, because sometimes I just want something new. So something that makes a pretty glossy cake is whipped frosting. Not as easy as traditional icing but I am sure you can do it. After all if I can do it - you can. This was on a lemon cake with lemon custard and lemon jelly in the middle. Tart and sweet can't be beat. Other things that would be good - gooseberry, blueberry, cranberry, current, blackberry, lindonberry, etc.
