Tutorial: Icing Consistency 101 - The Basics

When it comes to decorating cookies (or anything) with Royal Icing, the most important thing is consistency.  If your consistency is off, your details wont come out like you want them.  If it's too stiff, it struggles to come out of the icing tip or wont lay down for a smooth flood.  If it's too thin, your perfectly piped details run into each other and your flood runs over your edges all too make one big runny mess.

So yes, consistency is key.
