One sure sign of a genuine specimen of folk cuisine is an abundance of old family recipes which are generally similar but differ in details. Stack Cake is the real thing -- you can collect as many "authentic" recipes for stack cake as you would like. Stack Cake is made of 6 to 8 layers of cake with an apple-based filling between the layers. A common apocryphal story is that it originated as poor-folks' wedding cake, with several guests each contributing a layer.
