Different!

If you want something different for a wedding - then cancel the traditional cake, and get a Pork Pie Wedding cake.
I am informed they are becoming more and more popular, especially for couples who 'dare to be different'.  It seems to make a lot of sense to me - more use than the usual cake.
(I could be biased, but I love a good pork pie - and Bolster Moor Farm Shop have a history of winning Pork Pie competitions)
