Please can you help.  In keeping with tradition, the top tier of my
wedding cake has been kept, wrapped up in black tissue paper, then cling
film and finally sealed in a container pending our first born when it is
to be re-iced etc etc etc as a christening cake.  Well no children so we
thought it would be a good idea to bring it out for our 10th
anniversary.

My question is - Will it be OK to eat - common sense tells me absolutely
not - tradition tells me that it will be fine providing it has been
sealed properly. How can I tell if it is fine or not?  I'd hate to
poison our friends ;-)

It is a rich fruit cake, baked in 1989 and covered in marzipan and
icing, all home made by a proper baker.

Thank you in anticipation       Cathy MacDonald
