with the Doctor Who 50th anniversary coming up this weekend I had planned to bake some cakes with the character silicon molds from Lakeland.
http://www.lakeland.co.uk/18037/Doctor-Who-Cake-Pan To emphasisethe details I was going to dust them with icing sugar (powdered sugar for the US folks) - but I wondered if there was any way to make the powdered sugar TARDIS blue - I have the food colouring that is exactly the right shade but rather than make up some blue icing, I would like to dust them?
