I have looked on the main 'icing recipes' article but i can't find a fondant recipe.

Total cake decorating rookie here, but i think fondant is the stuff i want. Mouldable clay stuff? I googled it and the results were SO different. Totally different ingredients. So, i figured i'd ask the pros.

I need to buy the ingredients tomorrow morning, so no stress or anything.

In case you are wondering I am trying to decorate a 'Toby the Tram' cake. At least the shape is easy enough! The colours i need are grey and brown. I figure the brown is easy enough, but not sure how you make black/grey.

Thanks in advance.
