I have green icing, I have swiss rolls, I have edible green glitter, I have grey icing. But what can I do to recreate the black bits and stripes etc that doesn't involve liquorice which we all know is the food of the Dark Side? If I went for more icing, I'd have to actually make black icing myself and can't guarantee I'd get the consistency right, plus it's a lightsaber and so is round and the icing will run - HELP!
