Can you help me? Do you have a good recipe that you can share. My recipe consists or merigue powder sugar and water...what am i missing?
What are you using this for? If you are decorating cookies and want them to be shiny, just use glace' icing.
some people spray their creations with cooking spray, like Pam, to get it shiny...you could try and see what happens.
Royal icing dries matte. But, you can add some corn syrup (in place of the water in the recipe) to get it to dry slightly shinier. Or, instead of a RI recipe, you can try a glace recipe, which also dries shinier than RI.
I did an experiment where I compared the two a little while back. Here's the link in case you want to see the differences...

If you are unfamiliar with glace' here is a link to some cookies I made with it as well as the recipe I used and instructions.
