Tip

QUANTITIES FOR BUTTERCREAM
A ratio of equal quantities of icing sugar and butter works well unless you’re adding a significant quantity of a liquid (e.g. juice of an orange or lemon or melted chocolate). If you are, you can increase the quantities of icing sugar. You might want to add as much as double. Add gradually, if you like, and make sure it is sifted, to get the consistency you want.
KEEPING THE ICING
If you’re not using the icing straightaway, you can cover it and refrigerate for up to a week. Allow it to come back up to room temperature and beat again if necessary before using.

SHOULD I USE SALTED OR UNSALTED BUTTER FOR ICING?
Choose unsalted butter for a celebration cake. Salted is good for cupcakes.
