If making icing with shortening, you need to get the white shortening that is imported from the USA also known as Crisco. You can get it at any cake deco shops. It is not the same as the vegetable shortening you can buy at the supermarket here that you would normally use for cooking etc. If you can get your hands on the shortening from the USA it does make the icing so much more fluffy and even tastes nicer. Especially if you are wanting to make a white icing.
