Ok, now this one might need some explaining...

My brother had a bear-themed fancy dress party a few weeks ago, and I said I'd make cake for him if he came up with a concept. One of his friends suggested a severed hand - the result, I suppose, of an unlucky encounter with a bear.

So here it is:

I wanted it to look like a hand when you cut through it so I dyed the cake mix pink with food colouring before cooking it, then carved out some channels for bones made from icing once it came out of the oven.

The hand with the icing for bones in position. Probably not anatomically correct, but I did remember to put two bones in from the arm - the ulna and radius. And yes, I did just have to Google their names :-).
Making the rest of it was fairly pedestrian - just covering the cake with marzipan and ready-to-roll icing. The end result, however, was pretty gruesome. (The blood is some raspberry jam my brother made last month from the leftovers from a summer pudding I'd made).
