Soutra there is always a fave one though! 
Yes, Greenfinch I remember the Kunzel cakes too [surely the German spelling would be that as the other spelling would be French?]I remember the first time I had any was at a Christmas party when about 10 years old at school.It seemed very adult and sophisticated to eat one[and delicious.] Don't know what I would make of them now though.The russian slices that I mention in the first post on the thread, were all bits and bobs of cake welded together with rum essence in a slice with icing on top, they were heaven.Maybe nobody remembers them or they were just a local thing? You can still buy custard slices though [I bought 2 last week in Tesco.]Rum babas used to be popular in the 70's, and I downed quite a few of those as well.
