Please let me know if you add flavoring and which one you used. I am going to the store to get cream of tartar to make it too. I am curious what if will taste like. I haven't made it before. I made the no fail sugar cookies and they turned out great!
I added lemon extract to it once.. it was very good
You can add flavorings to it, but you might want to be careful with the ones you add. Since it is royal icing I don't think I would add anything with oil in it. For example, I have imitation almond and pure almond extract. Since her icing is royal icing, I wouldn't use the pure kind since it has oil in it. The oil may be enough to break down the royal icing and it won't set up like it should.
Hope the helps!!
