I read that you should line satin ribbon with wax paper when wrapping a cake with buttercream frosting. Does that apply to fondant covered cakes as well?
Well, technically, ribbon is not a food safe product. So, it should have a barrier. I am not in business and only do this for family and friends, but I have and have not used a barrier.
I guess it would depend on the fondant. I have seen some fondant have a sticky, greasy look to it. My guess is it might stain the ribbon. I have also seen fondant that appeared dry with a matte finish. I think it would be ok on that, just add the ribbon last.
I meant to say when I did line the ribbon, I used press and seal saran wrap.
i don't think ribbon has anything in it that is worse than anything else that cakes are exposed to. I mean, you have them in cars, outside with bugs, pollens, pollutants, curious guests touching them..... plus, they are probably only having one piece of cake, i doubt ribbon on it would hurt anyone.
but, no, you wouldn't need wax paper backing on fondant, how ever, if you are gonna bc "glue" it in place, you might want wax paper at those points so the grease in the bc won't absorb into the ribbon
