Not a recipe ... here's how I do the cream cheese icing ....
Cream the Cream Cheese with a little butter.
Add a little lemon juice and cream some more.
Mix in sifted icing sugar.
If too thick, or you want a little more flavour zip ... a little more lemon juice.
Make more than you think you need, as you can never have enough!!
And if there is too much, you can put it in the freezer, ready for another time.
