I LOVE working with Royal Icing.  LOVE it!  It is my preferred decorating technique for flowers, because a) it cleans up EASILY, and b) you can do a huge variety of flowers with all sorts of tips, but, you can also do a lot with just a few basic tips!  Royal icing is easy to control, can be easily applied to cakes, cupcakes and cookies, and creates a polished finish on any/all of your products.  

Here is a video on how to make your own!  All you need is icing/confectioners sugar, merginue powder and water.  Oh, ya, you probably need a mixer . . . or you might go crazy mixing by hand.

 Simple, easy and clean! 

Royal Icing Ingredients:
4 cups icing sugar (400g)
3 level tablespoons meringue powder
5-6 tablespoons water

Procedure:

To the bowl of a stand mixer add all meringue powder, and icing sugar.  Slowly add half the water and turn on the mixer to medium.  Add the rest of the water and turn the mixer up to full speed and allow it to mix for around 8-10 minutes, or until the icing is soft and fluffy.

If you are looking for a meringue powder substitute, you can also make Royal Icing by using egg whites. 

2 large egg whites (60g)

2 teaspoons fresh lemon juice

3 cups icing sugar (300g)

 Mix it together and continue as above.
