I have noticed some cookies with royal icing seem to be more glossy/shinny than others, do you add anything other than the standard royal icing recipe?
There is royal icing and then there is glaze. The glaze is shinier. Use the search function to find the glaze recipes. I haven't tried it yet.
Pastry galaxy, I did see a glaze recipe, I believe it has corn syrup in it. Thanks
Yes the Corn Syrup icing is the way to go. I use the recipe from Karens Cookie website. I have used that recipe heaps of times and it is great.
I've used a glaze before, but it's opaque unless you add white food coloring to it. That's the only draw back I had, that and it doesn't dry rock hard like royal icing does. I used the one by GeminiRJ on here: http://www.cakecentral.com/forum/t/681224/cookie-icing
In place of the white food coloring (that I can only find online) I used that Wilton cookie icing since it is really thin and bright white. It comes in a bottle at the grocery store (kinda looks like a glue bottle you use in school, ha ha).
