Whereas cake isn't even a foodstuff; it's such a broad spectrum of objects that its multi-variable nature (icing yes/no; cream yes/no; egg yes/no; hot yes/no;) means that it can still be revised down until there is only one variable. Hence, cake is revisable, but black forest gateau isn't ("was this made with cherries, cream and cocoa sponge yes/no?"), and until you reach that point, all other variables are dispensible.
