I've been practicing for a wedding cake I am making in a couple of weeks. It will have a black fondant ribbon around it. I put it on my practice cake, but it looks dull. I brushed on some vegetable oil, but I don't really like it. It doesn't look uniform, looks a little spotty. What else could I use or should I apply the veg oil in a different manner?
You can try shortening just a little and rub it on it leaves fondant shiny
You could spray soeme pam on in and then use a brush to even out the spots.
You could try using pearl luster dust....since you're practicing first.
With pearl dust you need to match the color because light pearl dust on dark fondant doesn't work right. There is a pearl spray and if you want something like a patent leather shine mix corn syrup and vodka (40/60 mix) and paint it on. It does take time to dry though.
Confectioners glaze will brighten it up without giving it a patent leather look. You can thin the glaze with a little alcohol to tone down the brightness. (I wouldn't recommend using confectioners glaze thinner to thin it out because I'm not sure it's edible. It does do a great job of cleaning the tools, tho.)
If you decide to try the confectioners glaze, you'll want to apply it after the ribbon is on the cake. If you glaze the ribbon before placing it on the cake, the fondant may dry out before the glaze is dry enough to touch. Want to avoid fingerprints, as well.
