These babies are part of my precious collections. I don't use artificial additives as far as I concern. And I always wanted to make something for children which are made of all natural ingredients ; no artificial colouring, no baking powder or baking soda, no artificial flavoring... Especially colouring is something pretty important when comes to children's food. :-) When I have my holidays to Japan (next coming), I will definitely bring back the whole collection of these babies!
Basically, they are made of vegetables, and stuff like Squid ink for the black. Purple is made of the skin of Japanese potatoes, red, pink, yellow... made of some flowers.... So I am feeling totally save to use them for all my bakes!
