I have seen such pretty cakes here. I love the ones with the shimmery shine to it. Is that disco dust? how do I apply it?
I like to use a make up brush the kind that you would use to put loose powder. It works well
I dip a fluffy brush in the disco dust, and then tap the brush gently over the cake.
Disco dust is NOT edible--non-toxic, but not to be eaten. It's for decoration only because it's finely ground PLASTIC.
When putting it on decorations that will be removed from the cake before serving, you can spray on some clear drinking alcohol and then sprinkle on the dust or gently press the item into the dust. You can also apply a thin coat of piping gel or shortening and do the same.
i suspect what you are seeing is actually pearl dust, usually edible.
