How do you get the royal icing to shine even after drying? I used meringue powder and they always have a dull finish after drying.

I use glace

Or use color flow.

I've heard that you can get Royal icing to dry with a bit of a shine by drying it under a desk lamp but haven't tired that myself.

Members here have suggested adding some corn syrup to the recipe.

royal icing does dry matte. glace dries shiny.

However, I've added corn syrup (during the last 2-3 minutes of mixing in the mixer) and gotten some shine on my royal icing without changing the consistency or drying time. I've used up to 1/3 cup in place of some of the water in the recipe (I use Antonia74's RI recipe).
