Ok just to start off HERE is an example of a successful copy! It was pretty fun. I read the ingredients on the packet and did my best to make a copy! Obviously i wasn't able to add the chemicals (I guess they were preservatives... don't need that in our house with 3 locusts... ahem... kids! ). But I did use all the obtainable ingredients like currents, flour and golden syrup etc.

Has anyone ever done this? Please share! As well as being "better" do you think it was cheaper to make yourself?
