sorry to be a pest, but I am really trying to learn new stuff, I want to do some cookies and I see most use RI, but I don't have meringue powder, I think I can use egg whites right???????
also what is VANVAN, brought this in a cake supply store just walking around wasting money!
TIA a thousand time 
just went to cooks.com and the recipe calls for cream of tartar, I don't have either in my house.

Royal icing is traditionally made using egg whites. A lot of people however avoid using egg whites because of the risk of salmonella. You can also use pasteurized egg whites.
Yes traditional royal icing is egg whites and PS mixed to the desired consistency. This is the only way I make it (although I sometimes add cornstarch and cream of tartar for strength when using the RI for structural items like pastillage display pieces or gingerbread houses).
