I just made this icing... it's a nice rich fudge icing, so you only need a very thin layer (I put them on chocolate cupcakes). I forgot about the water until after I incorporated the corn syrup before the icing sugar. But I think that was correct, because my Baking&Pastry book from the Culinary Institute of America also says to add the water at this point. The book also suggests to store at room temp in a sealed container.
I just made this icing to put on my favorite chocolate cake. Suprisingly it was scrumptous in flavor. I added an extra 3 ounces of butter for a moister texture and you will need to add extra powdered sugar to get the spreading consistency that you desired. I have found my chocolate icing for my chocolate cake. Once you make a few adjustments, trust me, you will fall in love with this recipe too.
