How do I make my white fondant shiny like a satin ribbon on a gift box?
Maybe some pearl dusts?
If you want it patent leather shiny, you can steam it.
I've rubbed a small amount of crisco over my fondant to get mine shiny.
Here's some cupcakes i did to get the shiny look:
I've also read mixing equal parts vodka & light corn syrup. This will become dry to the touch but still retain the shine (or so i've read, not tried this version myself).
There are also lustre sprays you can buy, if you want it pearl like.
