I was told I could luster dust chocolate. I tried this on some chocolate I poured into molds. It was white chocolate and I tried dusting with gold and silver. YOu could see it slightly and although it did shimmer, I just did not get nice thick gold or silver color. Any suggestions on how to do this better.

you might get better results if you mix the dust with some alcohol, like vodka, and paint it on.

you can mix it with alcohol and brush that on.
You can paint the inside of your chocolate molds with the luster dust "dry" which is just ok.

but I found that the best color options are to
You can mix cocoa butter with power colors for chocolate and brush this on molds or acetate sheets and then pour in your melted chocolate over it and when set pop that out or peel off the sheets.

hope this helps
