A slab of marble.

Inspired by The Great British Bake off to make a cake tonight, it was supposed to be a chocolate and orange marble cake but we didn't have any oranges so I used lemon rind instead (I know, sounds weird but it did work). I wanted it to be more marbly but I had to transfer it from tin to tin so it did get mixed a bit..also I just went crazy with the icing so it was a bit of a mess, it did taste nice though!
