haha! i read somewere that a jaffa cake is misleading. the difference between a cake and a biscuit is a biscuit should crumble, also you can dip it in tea. there was some reason that they benefitted in calling it a cake and got away with it but ive lost myself somehow...
ah yes thats it! biscuits uneaten go soft, cakes uneaten go hard, what happens to an old jaffa cake then, ive never left one long enough to see!
