Forgot about this thread - was staying at the Britannia Hotel near the Arthur Conan Doyle Hall. Was all a bit rushed on the afternoon in question but found a place that did deep fried chocolate. They wouldn't fry outside stuff so just made him a cock out of a Mars bar and a couple of garlic mushrooms held together with a paperclip. He liked it (and finished it)
The geezer in the shop had literally no clue what I was asking him for until I'd finished my sculpture, then the penny dropped
Thanks for the help, I do appreciate the serious foodie answers even if it's clear now I was after something far less cultured...
