I made a wedding cake a year ago last September and there was an extra layer which I put aside for future use. Now my aunt is having a b'day party and my eye has lit upon it. It has been wrapped (un-iced, un-marzipanned) in double foil with whisky poured on from time to time... some of the foil had actually stuck to the top of the cake (looked horrible tbh, bit black around the edges) but I sliced the whole top layer off and it looks pretty nice actually.
so.... how long does rich fruit cake really keep for...?
